Initial Start-up
1
Place the instrument on a clean, sturdy table or bench. It is important to keep the
instrument in a clean, relatively dust free environment to ensure optimal
performance.
2
Connect the power cord to the back of the instrument. Before connecting the
instrument to the main electrical supply, check that the AC voltage is appropriate
for the instrument.
3
Turn on the power switch on the rear panel. The LCD will display the version
number of the on-board firmware. After about three seconds, the instrument will
perform an initial self-diagnosis that requires about fifteen seconds. The Login
Screen will now be displayed for you to choose your user level (administrator or
common user), and enter the password (Initial password: 00000). Please allow
three minutes for the instrument to warm up (reach thermal equilibrium) before
reading plates.
4
Install the printer paper (if the optional internal printer is installed). The thermal
printer paper is treated on one side only and must be properly installed for the
printer to function. The side of the paper that faces out from the roll is the treated
side.
a. Open the rear cover of the instrument.
b. Tear off a small piece at the beginning of a new roll at an angle to form a point.
c. Place the roll of paper in the small pan-like holder positioned below the printer.
The roll should be positioned so that it will feed from the bottom.
d. While pressing the PAPER FEED key, feed the pointed end of the paper into
the paper feed slot in the underside of the printer until the printer grabs the
paper and feeds it through the slot in the top of the instrument.

Operation
Instrument Overview
The Model 680 Microplate Reader has built-in software that allows the user to set the plate
reading and data analysis conditions as a protocol data, read a microplate under the defined
reading conditions, and get the printout reports from the internal or external printer. The
software communicates through the 4-line, 20-character LCD and is controlled through the
instrument's membrane keypad.
The display shows the current mode of the on-board software. The software has three
different protocol types: End-point analysis, Kinetic analysis, and the Checkmark validation
protocols. The user presses the Memory Recall key to select analysis mode passing through
the choice of the protocol or the collected data.

Functions Overview
4.2.1 Calculations
The Microplate Reader uses Beer's Law to calculate the absorbance value of each well.
Beer's Law states that absorbance is equal to the log10 of the ratio of the baseline
measurement intensity (Io) to the sample measurement intensity (I).
Beer's Law
Absorbance = Log10 (Io/I)
Before measuring the plate, the reader takes a reading for all eight photodiode channels.
These values are recorded as the baseline measurement (Io) values for each channel,
respectively. The reader then records the sample measurement (I) value for each well, and
calculates the absorbance using these values. Channel-to-channel error is significantly
reduced because the Io value for a given channel is used only in determining the absorbance
of the wells of that channel.
4.2.2 Security password
The Model 680 Microplate Reader requires user login with password. This security feature
helps to prevent any unwarranted modifications to the analysis conditions/protocols and data
stored in the instrument, and identifies operator on reports. The reader has two user settings,
the Administrator and the Common user. Each user level has its own security password.
4.2.3 Memory Back-up
The battery back-up provides memory even after the reader is turned off.
The following information will be saved in the memory until new reading parameters are set
by the user or a new plate is read by the instrument. Note that if a run is aborted before it is
finished, all the previous plate reading data remain in memory and none of the data from the
aborted reading is stored.
1.
10 latest plate reading result for End-point protocol
2.
2 latest sets of Kinetic plate reading result (Max 30 series of readings for each
Kinetic)
3.
64 End-point Protocol settings and 2 Kinetic Protocol settings
4.
A set of Checkmark reference data and one latest set of Checkmark reading
result
5.
5 set of Standard curve data for the storage of standard curves and graphs
6.
8 wavelength values for filters
7.
Laboratory name
8.
Two security passwords (for the Administrator and the Common user)
9.
External printer type (ASCII or ESC/P type)
In addition to the battery back-up memory, the instrument has a small amount of none volatile
memory to keep the system information after the battery is dead. The Serial Number is stored
10
in this memory.
The first time the instrument is turned on, or after a battery failure, the following default
information will be held in the memory.
1.
Both of Administrator and Common user security password are set to "00000".
2.
Laboratory name is "Bio-Rad Laboratories".
3.
All wavelength values of the filters are set to "---" nm.
4.

and 0 minute.
5.
None of plate reading data is available.
6.
End-point protocol is chosen and the protocol number is set to #1.
7.
None of Standard curve data for the storage of standard curves and graphs is
available.
8.
External printer type is set to ASCII type.
4.2.4 Limits
The Microplate Reader displays absorbance readings with absolute values as 3.500.
Out-of-range absorbance values, i.e. those with absolute values greater than 3.500, are
displayed as either "*.***" or "-*.***". For example, if the absorbance is 4.500, then the display
will read "*.***", and if the absorbance is -4.500, the display will read "-*.***".
4.2.5 Reports
The Microplate Reader can generate nine types of reports for End-point protocol: Raw data,
Absorbance, Limit, Matrix, Cutoff, Curve fit, Concentration, Difference, and TeSeE Screening
report. And four types of Kinetic protocol can be generated by the reader: Absorbance,
Kinetic Plots, Linear regression, and GALT report.
Reports of End-point Protocol
(1) Raw data report
The Raw data report is the uncorrected absorbance values (without blank
subtraction). In single-wavelength mode, the reported value is the measured
absorbance. In dual-wavelength mode, the reported value is the difference between
the uncorrected readings taken with the measurement filter and with the reference
filter.
(2) Absorbance report
The Absorbance report is the blank-corrected absorbance values. The mean
absorbance value of all of the wells designated as assay blanks is calculated and
then subtracted from all 96 values of the raw data set to produce the Absorbance
report.
Abs = Raw – Blank mean
11
Blank mean = X/n
S.D. = [{X^2 – n*(Blank mean)^2}/{n-1}]^1/2
Where:
S.D. = Standard deviation
X = Sum total of the raw absorbance for each blank
X^2 = Sum total of the squared raw absorbance for each blank
n = Number of blanks
(3) Limit report
The Limit report provides a qualitative YES/NO report. Wells with blank-subtracted
absorbance values between the upper and lower limits are represented with an
asterisk (*), wells with absorbance values below the lower limit by minus signs (-),
and wells with absorbance values greater than the upper limit by positive signs (+).
(4) Matrix report
The Matrix report provides a qualitative report of the relative magnitude of the
absorbance values on the plate. The absorbance range defined by the upper and
lower limits is divided into 10 equal partitions, numbered 0 through 9. The
blank-subtracted absorbance value of each well is classified according to the
partition of the matrix to which it corresponds, and is reported as a signal digit. Wells
with absorbance values greater than the upper limit are reported by plus signs (+),
and wells with absorbance values less than the lower limit by minus signs (-).
(5) Cutoff report
The Cutoff report provides a qualitative report of the relative magnitude of the
absorbance values or converted concentrations on the plate.
Four types of cutoff report are supported as listed below.
a. Cutoff Constant
Ranged Cutoff Constant
The user inputs Positive and Negative values to be used as the cutoff.
For units designated "Abs", if the absorbance of a well is within the positive and
negative cutoff values, the well is scored "*". If the absorbance of a well is
greater than the positive value, the well is scored "+", and if the absorbance of a
well is below the negative value, the well is scored "-".
For units not designated "Abs", the absorbance value of each well is converted
to the concentration value using the curve fit constants of the curve fit report. If
the concentration of a well is within the positive and negative cutoff values, the
well is scored "*". If the concentration of a well is greater than the positive value,
the well is scored "+", and if the concentration of a well is below the negative
value, the well is scored "-".
Single Cutoff Constant
The user inputs Positive and Gray zone values to be used as the cutoff.
For units designated "Abs", if the absorbance of a well is within the gray zone
value of the positive cutoff value, the well is scored "*". If the absorbance of a
well is more than the gray zone value and greater than the positive value, the
well is scored "+", and if the absorbance of a well is more than the gray zone
value below the positive value, the well is scored "-".
12
Upper cutoff absorbance = Positive absorbance + ((Gray zone/100) * Positive absorbance)
Lower cutoff absorbance = Positive absorbance – ((Gray zone/100) * Positive absorbance)
For units not designated "Abs", the absorbance value of each well is converted
to the concentration value using the curve fit constants of the curve fit report. If
the concentration of a well is within the gray zone value of the positive cutoff
value, the well is scored "*". If the concentration of a well is more than the gray
zone value greater than the positive value, the well is scored "+", and if the
concentration of a well is more than the gray zone value below the positive
value, the well is scored "-".
Upper cutoff conc. = Conc. of positive controls + ((Gray zone/100) * Conc. of positive controls)
Lower cutoff conc. = Conc. of positive controls - ((Gray zone/100) * Conc. of positive controls)
b. Cutoff Control
Ranged Cutoff Control
The mean absorbance values of the Positive and Negative wells defined in the
plate map are used for the cutoff.
The absorbance range of the Positive and Negative is divided into 10 equal
partitions, numbered 0 through 9. The absorbance value of each well is
classified according to the partition of the matrix to which it corresponds, and is
reported as a signal digit. Wells with absorbance values greater than the
Positive are reported by plus signs (+), and wells with absorbance values less
than the Negative by minus signs (-).
Single Cutoff Control
The mean absorbance value of the Negative wells that defined in the plate map
and the gray zone value that is entered by the user are used to the cutoff. The
upper and lower cutoff values are:
Upper cutoff absorbance = Mean of negative controls + ((Gray zone/100) * Mean of negative controls)
Lower cutoff absorbance = Mean of negative controls – ((Gray zone/100) * Mean of negative controls)
The absorbance range of the upper and lower cutoff is divided into 10 equal
partitions, numbered 0 through 9. The absorbance value of each well is
classified according to the partition of the matrix to which it corresponds, and is
reported as a signal digit. Wells with absorbance values greater than the upper
cutoff are reported by plus signs (+), and wells with absorbance values less than
the lower cutoff by minus signs (-).
c. Cutoff Formula
The mean absorbance values of the Positive and Negative wells defined in the
plate map are used for the cutoff formula calculation.
The 12 types of formula supported are:
i.
ii.
iii.
iv.
v.
vi.
k * CNx
k * CPx
k * COx
CNx / k
CPx / k
COx / k
vii.

xi.
xii.
13
k + CNx
k + CPx
k + COx
k*CNx + CPx
(CNx + CPx) / k
k1*CNx + k2*CPx
The result absorbance value of the formula calculation and the gray zone value
that is entered by the user are used for the cutoff. The upper and lower cutoff
values are:
Upper cutoff absorbance = Result of a Formula + ((Gray zone/100) * Result of a Formula)
Lower cutoff absorbance = Result of a Formula - ((Gray zone/100) * Result of a Formula)
The absorbance range of the upper and lower cutoff is divided into 10 equal
partitions, numbered 0 through 9. The absorbance value of each well is
classified according to the partition of the matrix to which it corresponds and is
reported as a signal digit. Wells with absorbance values greater than the upper
cutoff are reported by plus signs (+), and wells with absorbance values less than
the lower cutoff by minus signs (-).
d. Cutoff Ratio
The mean absorbance value of the Calibrator wells defined in the plate map and
the concentration value entered by the user are used for the cutoff ratio. Before
the cutoff, the absorbance value of each well is converted into the concentration
value. The ratio of Concentration/Absorbance of Calibrator is applied to the
conversion. Then, the cutoff is done with the defined Positive and Negative or
the defined Positive and Gray zone values.
Ranged Cutoff Control
The concentration range of the Positive and Negative is divided into 10 equal
partitions, numbered 0 through 9. The concentration value of each well is
classified according to the partition of the matrix to which it corresponds, and is
reported as a signal digit. Wells with concentration greater than the Positive are
reported by plus signs (+), and wells with concentration less than the Negative
by minus signs (-).
Single Cutoff Control
The concentration value of the Negative and the gray zone value entered by the
user are used for the cutoff. The upper and lower cutoff values are:
Upper cutoff concentration = Positive + ((Gray zone/100) * Positive)
Lower cutoff concentration = Positive - ((Gray zone/100) * Positive)
The concentration range of the upper and lower cutoff is divided into 10 equal
partitions, numbered 0 through 9. The concentration value of each well is
classified according to the partition of the matrix to which it corresponds, and is
reported as a signal digit. Wells with concentrations greater than the upper
cutoff are reported by plus signs (+), and wells with concentrations less than the
lower cutoff by minus signs (-).
(6) Curve fit report
The Curve fit report provides a regression analysis based on the absorbance values
of a series of standards. There are ten types of curve fits supported with the
onboard software on Model 680 microplate readers:

4P Logistic Rodbard
5P Logistic Cook-Wilkenson
4P Logistic Cook-Wilkenson
5P Exponential
Sigmoid Logistic
Linear regression
Quadratic regression
Cubic spline
Point To Point regression
The onboard software calculates the best fit of the defined curve between each set
of two consecutive data points in the standard curve of absorbance vs.
concentration. And then it generates the report with the coefficients of regression,
the correlation coefficient, and the standard error.
For readers with the optional internal printer or with an external ESC/P printer which
accepts ESC/P code, a graph of the standard curve may be generated when
selected in the report parameter.
(7) Concentration report
In case of the curve fit, the Concentration report also provides the regression
analysis. After the calculation of the curve fit, it calculates the concentrations values
of the samples, and generates the report.
In case of the cutoff constant with the unit not designated "Abs" and in case of the
cutoff ratio, the reader generates the list of concentration of each well.
(8) Difference report
The Difference report is the subtraction report between the neighboring columns or
row.
(9) TeSeE Screening report
Analysis of the TeSeE screening assay results can be done with two
pre-programmed protocols: “TeSeE” protocol is stored in Endpoint Protocol
position #5 and “TeSeE eq” is stored in Endpoint Protocol position #6 as factory
default setting. Both protocols are locked.
TeSeE screening report is generated only if these protocols are selected as current
active protocol. Plate is first validated according to negative and positive controls
validation criteria; samples are then compared to the calculated cut-off.
Criteria for plate validation are set as follow:
Criteria #1:
Individual Negative Control must be < 0.150
Number of valid Negative Control must be >= 3
Criteria #2:
Individual Negative Control must be < 1.400 * Negative Control average
Number of valid Negative Control must be >= 2
Criteria #3:
Positive Control average must be >= 1.000
Cutoff is calculated as follow:
TeSeE:
Positive cutoff = Negative Control average + 0.210
15
Negative cutoff = (Negative Control average + 0.210) * 0.900
TeSeE eq:
Positive cutoff = Negative Control average + 0.210
Negative cutoff = Negative Control average + 0.090
Samples are interpreted as follow:
“POS”:
Positive when sample OD >= Positive cutoff
“NEG”:
Negative when sample OD < Negative cutoff
“???”:
Gray zone: NEG cutoff =< sample OD < POS cutoff
Reports of Kinetic Protocol
(1) Absorbance report
The Kinetic Absorbance report is the series of absorbance data in the kinetic
sequence.
(2) Kinetic Plots
The Kinetic plots are the absorbance plots of each well in the plate. It is available for
readers with the optional internal printer or with an external ESC/P printer which
accepts ESC/P code.
(3) Linear Regression report
The Linear Regression report provides the calculation of Kinetic reaction rate for
each well using the linear regression.
(4) GALT report
The GALT report calculates the following formula for each well between two
readings of a plate.
GALT = (R2 – R1) * k
Where:
R1 = Absorbance value of 1st reading
R2 = Absorbance value of 2nd reading
k = GALT factor
4.2.6 RS-232C Interface
The Model 680 Microplate Reader has a built-in bi-directional RS-232C interface (9 pin D-sub
connector, Bio-Rad catalog number: 168-1005). This allows external computers to control the
instrument. When an external computer is in control of the microplate reader, the printer and
the membrane keys, except for the "Start/Stop" key, are automatically deactivated and the
LCD display as below.
Remote mode
The reader will remain in remote control mode until it receives "RL" command from the host
computer or until the "Start/Stop" key on the microplate reader is pressed.
16
4.2.7 Printer
The Model 680 Microplate Reader has a built-in printer interface connector (25 pin D-sub) or
an optional factory built-in printer.
The printer interface connector allows the user to connect an external printer for the printout
of reports or protocol. This external printer interface is based upon Centronics interface
standards.
Two types of printer, ASCII type and ESC/P type, are allowable to connect. The ASCII type
printer can only accept ASCII character based codes which does not include any graphic
codes. Next, the ESC/P type printer can accept ESC/P codes which include graphic codes.
The optional factory built-in internal printer and the external ESC/P type printer can generate
all types of report including graphs and kinetic plots.

If the selected language is difference from the previous
language, the reader will clear all of memories and will be set
to the initial condition. At that time the battery error screen
appears, but it is not an actual error.
NOTE:
The details of the initial condition are described at the
memory back-up section. See section 4.2.3 for Memory
Back-up.
2. Deference between English and Chinese version
There are some functionality differences between the English and the Chinese version as below.
(1). On-board storage of standard curves and graphs
The Chinese version does not support the on-board storage of standard curves and graphs. Therefore,
saving and recalling of a standard curve is not available for Chinese version.
(2). Automatic mapping function for the plate mapping
The Chinese version has the function of automatic mapping, but it is an old style. It does not allow the
user to input each number of the well types for a plate map.
(3). Cutoff formula
The Chinese version supports only five types of the cutoff formula. The supported formulas for Chinese
version are as follows.
i.
K * CNx
ii. K + CNx
iii. K*CNx + CPx
iv. (CNx + CPx) / K
v. K1*CNx + K2*CPx
(4). TeSeE Screening Report
The Chinese version does not support TeSeE and TeSeE eq screening report. Endpoint Protocol #5 and
Endpoint Protocol #6 for Chinese version is worked as a normal endpoint protocol. The UTSE command
and DTSE command in Command Language does not function in Chinese version.
40
(5). Retrieval function for plate data
The Chinese version does not support this feature. The URPD (Upload Raw Plate Data) and DRPD
(Download Raw Plate Data) command in Command Language does not function in Chinese version.
(6). Serial number input/output
The Chinese version does not support Serial number input/output. It means that the serial number does
not appear in the head line of each printout report.

Installing Interference Filters
With the power off, open the rear cover of the instrument by pressing
the release latch located on the top left portion of the cover.
The filter wheel is located on the left side of the instrument. Note that
the filter wheel has eight filter positions.
Rotate the filter wheel to the desired filter. Grasp the top of filter
frame and pull up to remove the filter.
Insert the new filter into the desired filter position.
Ensure that the new filter is added to the filter list as follows: Main
menu->Edit->Filters.
Changing the Lamp
With the power off, open the rear cover of the instrument by pressing
the release latch located on the top left portion of the cover.
Remove the two screws on the black plastic cover and carefully
remove the plastic cover.
Remove the screw on the metal cover. Lift the cover up and away
from the instrument. This will allow the lamp to be pulled free from the
lamp housing.
Holding the ceramic base in one hand and the lamp housing in the
other, carefully pull the lamp free of the base.
Carefully insert the new lamp firmly in the ceramic base. Apply even
pressure when inserting the lamp so that the bulb dose not become
misaligned in the reflector housing. Be extremely careful not to touch
the front glass of the lamp during installation.
Position the new lamp into the housing so that the plastic guides hold
the flange of the lamp.
Carefully place the metal cover over the lamp. Tighten the screw.
Replace the plastic cover and tighten the screws.
Close the rear cover.
