© Open the battery case on the back of the
unit and insert the battery.
Be sure the battery is properly aligned.
@ Attach the ring plate to the slide pole.
© Attach the red side of the sensor to the
red terminal and blue side to the blue
terminal. Push the slide button and attach
the remaining to the terminal.
@ Turn the power switch on and check the
diplay. When the display indicates room
temperature, it's ready for use.

o Place fresh solder on
the tip and apply the
tip to the point to be
measured.
The temperature will
be displayed in 2to 3
seconds.
O Turn the unit off while it is not use.
|4.Precaution ||
© The sensors are made of very thin (0.25)
CA wire. Handle them with care. Do not
apply heavy pressure or they will break.
@ The body is made of plastic. Do not touch
the body with the soldering tip.
© The measuring point is coated with a
special metal alloy which will wear away
after repeated measurements, resulting in
maccurate readings. Replacing the sensor
with a new one will restore the measuring
accuracy. The sensor has a useful life of
approximately 50 readings.
© Use alcohol to remove any flux adhering
to the terminal. Do not use thinner or
benzine.

Let the unit set a room temperature (68°F + 6° or 23°C + 3°) for at least 30
minutes.
Remove the 4 Phillips screws holding the 2 halves of the case together.
Leaving the battery in place, take the 2 halves apart.
Remove the 2 Phillips screws securing the PCB.
Turn the PCB over so that the component side of the board is accessible.
Remove the sensor wire from the posts on the cover and put a jumper wire
across the red and blue sensor posts.
Turn the power switch "on".
Note the room temperature and adjust the VR1 potentiometer (see figure 1) so
that the digital display is the same as the room temperature. CAUTION: Do not
touch the sensor RTH 1 (see figure 1) during this process. Doing so will cause
an erroneous reading on the digital display during adjustment.
Attach the leads from the regulated DC power supply to the sensor posts on the
191 or 191B: positive (+) lead tot he red post and negative (-) lead to the blue
post. If you are using a thermometer calibrator, skip instruction 11 and follow the
instructions for the unit. Use the VR2 to adjust the reading on the digital display.
Using the chart below, apply the three different voltages. The 191 display should
read the given temperature on the chart plus room temperature. If there is any
discrepancy between the 191 digital display and the chart below, adjust the VR2
until the digital display is correct. The factory tolerance on the 191 is
+5°F(£3°C). Note: When calibrating the 191B follow the same procedure as
with the 191 and convert to degrees fahrenheit.

If the unit cannot be calibrated, please call Hakko for an RMA number and send
it back for repair.
Screw the PCB back into place.
Screw the 2 halves of the case back together making sure the black plate
covering the switch is in place.

Standard DC source and DVM functions are
combined into one unit.
Because it is so compact, this intelligent portable
calibrator displays its real capability in the field.
Simultaneous displays for output
generation and input measurement
Output dividing function
The Model 2422 is equipped with a measuring function in
addition to the DC standard generator function which is
capable of generating DCV, DCmA and thermo-e.m.f.
This combination produces simultaneously displaying
of both generation and
measurement values on
its LCD display unit.
The Model 2422 calibra-
tor can cope with a wide
range of applications
which in the past have
required a standard
generator and a DVM.
Small and light weight
Because the Model 2422 is the size of a magazine and
weighs only 1.2kg (2.71bs), it has superior portability
which makes it ideal for field use.
[ен на
Auto stepping output function
Since the auto stepping output function is provided to
output dividing and set-value memory functions, itis very
useful for shortening service time when instruments
such as measuring and industrial instruments are
repeatedly adjusted and calibrated.
The Model 2422 is supplied with an output dividing
function which can divide and set the output set-value
freely from 1 to 15, and is therefore most suitable for
checking recorder linearity.
Set-value memory function
Output set-values corresponding to a maximum of 20
channels can be stored. Frequently used set-values can
be generated through one-touch key operation.
Direct thermometer calibration
The Model 2422 can generate DC voltage equa! to
thermo-e.m.f. by directly setting the temperature using
any of the 5 most frequently used thermocouple types
(Types K, E, J, T and R). In addition, an optional .
reference junction (RJ) sensoris available for calibration.
Built-in Ni-Cd battery/AC power
drive
The Model 242? has a built-in Ni-Cd battery to provide
the portability required of a field calibrator. It is also
supplied with an AC adapter which enables it to use AC
power supplies,
EL back lighting
The Model 2422 employs a large, EL back-lit display unit
on which set values and measured values can be easily
read, even under low light conditions.
The Model 2422 can cope with a wide range of
С applications such as field servicing
as well as equipment testing
and inspection in any lab.
