2.5.2 V-TIME /
Button
First Function - V/TIME
Displays all the secondary information available on the small display.
For Insulation Measurement:
• The time elapsed since the start of the measurement
• The voltage between the instrument’s “+” and “–” terminals
• Date, time, test voltage and OBJ:TEST number in memory recall mode (MR)
For Resistance or Continuity Measurement:
• Voltage between the instrument’s “+” and “–” terminals
• Date, time, test voltage and OBJ:TEST number in memory recall mode (MR)
Second Function -
Time-controlled Test
Displays the measurement duration programmed in SET-UP on the small display.
• The
symbol lights up.
• Pressing the START button begins the measurement process. The measurement
duration is set to 15 minutes by default.
• As soon as the measurement starts, the small display counts down the remaining
duration of the measurement. Once it reaches zero, the measurement stops.
• As the time-controlled test is carried out, interval samples (resistance/voltage values
as a function of time) are automatically saved. The time between each sample is set
to 30s by default, but it can be changed in the SET-UP menu.
• The samples are displayed with the R(t) function (see § 2.5.3) as long as a new
measurement has not been started. With each new measurement, the previous
sample value is erased from the memory. These sample values are saved with the
last value of the resistance if used with the MEM (memory storage) function.
NOTE: If the selector switch’s position is altered, or if the STOP button is pressed
during measurement, the measurement is interrupted.

2.5.3 R-DAR-PI / R(t) Button
First Function - R-DAR-PI
The R-DAR-PI button allows automatic measurement of:
• Polarization Index (PI)
• Dielectric Absorption Ratio (DAR)
These two parameters are useful on long cables, or when monitoring the aging of
insulation on electrical machines.
On this material, measurement is adversely affected at the beginning, due to interfering currents (from capacitive charges, dielectric absorption) which eventually
cancel each other out. Therefore, in order to get an accurate measurement of the
leakage current, it is necessary to carry out the measurement over a long period
of time, to reduce the influence of any interfering currents at the beginning of the
measurement.
Next we calculate the PI or the DAR ratios:
PI = R10 min / R1 min (2 values to record during a 10 min measurement)
DAR = R1 min / R30 s (2 values to record during a 1 min measurement)
The quality of insulation depends on the results found.
DAR
PI
< 1.25
State of the insulation

Inadequate, even dangerous
<2

Using the R-DAR-PI Function:
During or after measurement, the R-DAR-PI button allows you to scroll through
the following values:
• DAR (for measurements lasting > 1 min).
• PI (for measurements lasting > 10 min).
• Capacitance in µF (only after the measurement has stopped and the circuit has been discharged).
• Insulation resistance in MΩ, GΩ or TΩ.
Automatic Measurement of DAR or PI:
• If the button is pressed when in voltage measurement mode before proceeding with a measurement, the following is displayed:

DAR
www.ShopAEMC.ca
PI
1.877.766.5412
Megohmmeter Models 1050 /1060
Depending on the choices (DAR or PI), the measurement goes as follows:
a) DAR: Press START - the DAR symbol flashes and the display indicates “- - - -”
as long as the calculation of the coefficient is not possible (t < 1 mn).
e.g.:
DAR
After 1 min, the measurement stops and the main display automatically shows the
DAR value. During or after measurement, the R-DAR-PI button can be used to see
the insulation measurement carried out, but it does not give the PI value since the
measurement has not lasted long enough.
b)PI: Press START - the PI symbol flashes and the display indicates “- - - -” as long as the calculation of the coefficient is not possible (t < 10 mn).
e.g.:
PI
After 10 minutes, the measurement stops and the main display automatically
shows the PI value. During and after measurement, the R-DAR-PI button makes
it possible to display the DAR (after 1 min), the PI (after 10 min) and the insulation
measurement.
Note: If during DAR or PI measurement (automatic or not), a high external interference voltage becomes present, or the insulation resistance goes beyond the
device’s measurement range, then the DAR or PI measurements are interrupted
and the screen indicates:
DAR
MΩ
or
PI
MΩ
Note: The 10 min / 1 min measurement durations for PI calculation can be modified in the SET-UP menu (see § 2.5.7), allowing changes to standards or to suit a
particular application.
Second Function - R(t)
Used to access the interval insulation resistance values as a function of time after
a measurement in “time-controlled test” mode (see § 2.5.2).
The time between each saved sample is programmed in the SET-UP menu.
This function is also available on the Model 1050, which has neither a read-write
memory for saving measured data, nor an interface for data retrieval from the
instrument by a PC.
Model 1050:
Up to 20 samples can be recorded during measurement at the sample rate chosen
in SET-UP (the default value is 30 seconds). It is possible to save more than 20

Model 1060:
The number of samples that can be saved is only limited by the memory space
available.
To enter the display mode, press the R(t) button:
• The small display indicates the time 00:30 (e.g. the sampling frequency is
every 30s).
• The main display shows the corresponding R value.
Use the V/TIME button to alternate between the voltage and time (on the small
display), associated with the R value on the main display.
The
button is used to scroll down through the all the samples saved during
measurement, allowing you to read the information in order to draw R(t) and V(t)
graphs.
This makes it possible to carry out R(t) analysis on-site, without a printer or a PC.
To exit this function, press the R(t) or R-DAR-PI button again.

2.6 Measurement Functions
2.6.1 AC/DC Voltage
• Select any measurement position with the rotary selector switch.
• The instrument is automatically in AC/DC voltage measurement mode.
• The voltage is continuously measured and is shown on the small display.
Measurement is prohibited if an external voltage is present at the terminals
before pressing START/STOP. Similarly, if an interference voltage is detected
during measurement, the measurement is stopped and that voltage is indicated.
2.6.2 Insulation Measurement
As soon as one of the MΩ positions has been selected, the main display shows “- - - - MΩ”, and the small display indicates the voltage present at the device’s “+”
and “–” terminals.
If the external voltage present at the device’s terminals exceeds 25VAC/DC,
pressing the yellow START/STOP button does not bring about insulation measurement, but instead triggers an audible signal. The
symbol flashes for 2
seconds, then the device goes back to automatic voltage measurement.
If the external voltage present at the device terminals is below 25VAC/DC, then
insulation measurement can proceed.
ressing START immediately begins the measurement. The measurement value
P
is displayed on the main digital display and on the bargraph. An audible beep is
given out every 10 seconds to indicate that measurement is in progress.
If the test voltage is considered to be dangerous (>120V), the
symbol is
displayed. If, during insulation measurement, an external voltage >25VAC ±3V or
35VDC is detected, the measurement is stopped as long as the voltage is applied
to the instrument. The
symbol flashes and the voltage value is indicated on
the small digital display.
If the measurements fluctuate greatly, the SMOOTH function can be enabled (see
§ 2.5.5).
By pressing the V/TIME button during measurement, you can alternate between

Pressing the STOP button stops the measurement. After the measurement has
been stopped the result remains displayed.
It is possible to scroll through all the other results available on the main display
using the R-DAR-PI button. This button can also be used before the measurement
is begun (see § 2.5.3).
If the “time-controlled test” mode has been selected, the R(t) button makes it possible to access all the saved interval measurements automatically (see § 2.5.2 and
2.5.3).
If the ALARM function is activated, a buzzer is triggered as soon as the measurement crosses the threshold programmed in the SET-UP configuration menu (see
§ 2.5.4).

2.6.3 Continuity (40Ω
) / Resistance (400kΩ)
• Continuity measurement is carried out on the 40Ω switch position
(with a test current > 200mA up to 20Ω)
• Resistance measurement is carried out on the 400kΩ position
(with a test current < 6mA).
Once the selector switch has been turned to one of these 2 function positions, the
main display indicates - - - - Ω (for continuity) or - - - - kΩ (for resistance) and the
small display indicates the voltage present on the “+” and “–” terminals.
If the voltage is >3VAC/DC and the START/STOP button is pressed, the
symbol flashes and the audible alarm beeps (for 2 seconds) signaling that the
measurement was denied. The instrument then goes back to its normal voltage
measurement.
If the voltage is <3VAC and the START/STOP button is pressed, the measurement proceeds.

The main display indicates the continuity or resistance value in progress, while the
small display indicates the voltage present on the “+” and “–” terminals.
The R-DAR-PI, V/TIME and SMOOTH buttons are not active for these functions.
WARNING: If, during continuity or resistance measurement, an external voltage
>25VAC ±3V or 35VDC is detected, the measurement is stopped as long as the
voltage is applied to the instrument.
The
symbol flashes and the voltage value is indicated on the small digital
display.
If the ALARM function is activated, a buzzer is triggered as soon as the measurement crosses the threshold programmed in the SET-UP configuration menu.

CHAPTER 4
OPERATION
NOTE: Charge the instrument fully before use (Model 1060).
4.1 Measurement Procedure
• Start the instrument by selecting the corresponding position (MΩ, 40Ω
or 400kΩ) with the selector switch. All the segments on the LCD
screen are displayed, then the battery (or rechargeable battery) voltage
is displayed.
• Connect the leads to the “+” and “-” terminals and the points of
measurement.
• The input voltage is constantly measured and displayed on the small
display. If an external voltage is present that is greater than the thresholds
described in § 4.2, 4.3 and 4.4, then measurement is prohibited.
• Press the START/STOP button to start the measurement.
• Press START/STOP again to stop the measurement. The last result
remains on the display until the next measurement is started, or the
selector switch is turned.
WARNING: If a voltage >25VAC or 35VDC is detected during measurements,
the instrument indicates this voltage on the small display, the warning symbol
flashes and the measurement is stopped.
Note: There are several special functions that can be used (see § 2.5).
4.2 Insulation Measurement (see § 2.6.2)
This function allows the instrument to measure insulation resistance from 1kΩ to
40GΩ at a test voltage of 50V, 100V, 250V and up to 1TΩ at 500V and 1000V.
•
•
•
Use the rotary switch to select the required test voltage (MΩ-50V, or MΩ100V, or MΩ-500V, or MΩ-1000V).
Connect the instrument to the insulator to be tested.
Start the measurement using the START/STOP button and read the results.
WARNING: If the voltage present exceeds 8V for MΩ-50V, 16V for MΩ-100V, or
25V at all the other test voltages, then measurement is prohibited.
Scroll through the results on the main display with the R-DAR-PI button, or on the
small display with the V/TIME button.

Megohmmeter Models 1050 /1060
These values are available until another measurement is taken or the selector
switch is turned.
When measuring high levels of insulation (> 1GΩ), it is advised that the guard
terminal be used to eliminate the influence of surface leakage currents. The guard
is connected between the two measurement contact points, and the surface susceptible to surface currents, (e.g. dusty, damp cable or transformer insulation). In
this case, alligator clips are preferable to test-probes held in the hand.
As soon as insulation measurement is stopped, the test circuit is automatically
discharged using the instrument’s internal resistance.
4.3 Continuity Measurement (see § 2.6.3)
The measurement current is > 200mA from 0Ω to 20Ω and >140mA from 20Ω to
40Ω in this function.
This measurement serves to test the low resistance. The measurement ranges
increase automatically up to 40Ω with a maximum resolution of 0.01Ω.
•
•
•
•
Select the 40Ω position with rotary switch.
Connect the instrument to the test object.
If the voltage present is > 3V, then measurement is prohibited.
Start the measurement and read the results.
NOTE: It is possible to compensate for the lead resistance (see § 2.5.10)
NOTE: The R-DAR-PI and V/TIME buttons are not active for this function. There
is no automatic polarity change in continuity measurement.
4.4 Resistance Measurement (see § 2.6.3)
The measurement current is limited to 6mA in this function. The measurement
ranges increase automatically up to 400kΩ with maximum resolution of 0.01Ω.
•
•
•
•
Select 400kΩ position with the rotary switch.
Connect the instrument to the test object.
If the voltage present is > 3V, then measurement is prohibited.
Start the measurement and read the results.
During measurement, the potential difference at the input is indicated on the small
display (useful for measurement of multi-junction components: thyristors, high voltage diodes, etc).
The open circuit voltage is equal to the voltage of the instrument’s battery.
NOTE: The R-DAR-PI and V/TIME buttons are not active for this function.

5.2 Saving / Recalling Values (MEM/MR Button)
NOTE: After replacing or completely discharging the battery, the message “Memory
OFF” appears when you try to save a measurement in memory.
To be able to save your measurements, you will need to do the following:
Set the instrument to SET-UP and press the MEM button (the display shows “MEM
All clr”). Press the MEM button for 2s (the display shows “MEM ALL FrEE”). Measurements are now ready to be saved.
First Function - MEM (Save)
Results can be recorded in the instrument’s memory and stored along with
addresses defined by an object number (OBJ) and a test number (TEST).
An object represents a ‘box’ into which we can place 99 tests. Thus, an object can
represent
machine
or an

ments (insulation, resistance and continuity) are carried out.
ShopAEMC
34
Megohmmeter Models 1050 /1060
1) When the button is pressed, the MEM symbol flashes and the small display
indicates the first free OBJ : TEST number (e.g. 02 : 01). The main display
indicates “FrEE”.
• The OBJ number is the same as that of the last saved measurement, and
the TEST number goes up in increments of 1.
• It is always possible to modify OBJ : TEST with
and
.
• If the user happens to select a memory address that is already occupied,
then OCC appears on the main screen.
• If a new OBJ is selected, the TEST goes back to 01.
2) By pressing MEM once again, the present measurement results will be
recorded in the selected memory address (occupied or otherwise). The MEM
symbol stops flashing and remains displayed. The time and the date of this
recording are stored with the available data (R, V, t).
If a button other than MEM is pressed, or the selector switch is moved
before pressing MEM a second time, the instrument exits from MEM
mode without saving the results.
3) If a time-controlled test has been initiated, interval values (samples) are available. They are automatically saved under the same OBJ : TEST number as
the final measurement.
Memory Capacity:
• Total memory space: 128kb
• Data management: 8kb
• Free memory space: 120kb
An insulation measurement result takes up approximately 80 bytes. For a “timecontrolled test”, a sample takes up 10 more bytes. A resistance or continuity
measurement takes up 26 bytes. Therefore, it is possible to record about 1500
insulation measurements or about 4000 resistance or continuity tests.
Free Memory Space
This function is automatically activated when a result is saved.
Press MEM once to get the following free OBJ : TEST number; the bargraph displayed corresponds to the available free memory space.
• If the entire memory is free, all of the bargraph segments appear.
• If the entire memory is full, the arrow to the left of the bargraph flashes.
• As soon as the storage is complete, the bargraph disappears.
Each segment of the bargraph equals approximately 50 recordings.

Second Function - MR
The MR function allows a recall of any saved data from memory, regardless of the
position of the rotary selector switch.
• When the button is pressed, the MR symbol is displayed. The small display indicates the last OBJ : TEST number to be assigned (e.g. 02 :11).
• 02 “11” flashes opposite the TEST symbol. Use the and buttons to
select the desired OBJ : TEST number.
• If a new OBJ is selected, TEST is automatically set to the maximum
stored number. At this stage it is possible to review the entire memory
with the and buttons, since the measurement values corresponding
to the selected OBJ : TEST number are displayed on the main display.
Use the R-DAR-PI button to scroll through them.
• The V/TIME button gives access to the date / time/V/OBJ-TEST number
for each result.
• If the recording selected by the OBJ : TEST number corresponds to a
time-controlled test, the R(t) values can be accessed by pressing the
R(t) button. The small display changes and indicates min:sec (time of 1st
flashes on the screen. You can scroll through
sample) and the symbol
the other samples with the button.
To exit from R(t) mode and return to the normal memory recall mode (OBJ :
TEST), press R(t) or R-DAR-PI again. To exit the MR function, press the MR
button once again or turn the selector switch.
5.3 Printing Measured Values
(PRINT/PRINT MEM Button - Model 1060)
If you use a serial printer, choose the appropriate communication speed (communication rate) in the SET-UP menu, between 300...9600 communication, then
program the printer to the format run by the instrument (see § 5.1).
If you are using a parallel printer, you should set the communication rate to “Parallel” when in SET-UP and use the optional serial-to-parallel adapter.
There are two printing modes possible:
• Instantaneous printing of measurement (PRINT)
• Printing of recorded data (PRINT memory)
If the data transmission to the printer is successful, the COM symbol flashes
once on the screen. If a problem has occurred, the COM symbol remains on the
LCD screen without flashing.
