Multimeter with Temperature
Temperature
Adjust DC voltage (R4) before adjusting
temperature (R38).
The following describes three temperature calibration
procedures:
•
Calibrating at room temperature. Use this procedure if
it is not necessary to optimize the Meter's performance.
•
Calibrating in an ice bath. Use this procedure to
optimize the Meter's performance at around 0.0°C.
•
Calibrating in a lag bath. Use this procedure to
optimize the Meter's performance at room temperature.
Room Temperature Calibration
The following procedure allows you to make the calibration
adjustment at room temperature.
1. Allow the Meter to stabilize at room temperature. After
the temperature stabilizes, do not touch the COM jack.
Turn to temperature function and °C mode.
2.
3. Observing the correct polarity, connect a copper short
across the input jacks of the Meter (see Figure 5).
4. Using a temperature probe with the appropriate Meter
(Fluke 45 or equivalent), measure the temperature of
the COM input jack (see Figure 5). Be sure to place the
probe on the COM closest to the pca.
5. Adjust R38 so the Meter display is the same as the
temperature probe reading.
Ice Bath Calibration
The following procedure optimizes the Meter's performance
near 0°C (32°F) using a specific thermocouple.
Put the Meter in the temperature function and °C
1.
mode.
2. Insert a thermocouple in an ice bath (see
Figure 6).
3. Insert a mercury thermometer to the same depth as the
thermocouple wire to verify that the ice bath
temperature is 0.0°C .

Note
4. Connect the other end of the thermocouple wire to the
Meter using a Fluke 80AK Adapter Plug (see Figure 6).
Allow the instrument reading to settle.
5. Adjust R38 so that the Meter display has the same
reading of the ice bath temperature.
Lag Bath Calibration
The following adjustment optimizes the Meter's
performance at room temperature using a specific
thermocouple.
Put the Meter in the temperature function and °C
1.
mode.
2. Insert a thermocouple in a lag bath (see Figure 6).
3. Insert a mercury thermometer to the same depth as the
thermocouple wire to verify that the lag bath
temperature is at room temperature
4. Connect the other end of the thermocouple wire to the
Meter using an 80AK Adapter Plug(see Figure 6).
Allow the instrument reading to settle.
5. Adjust R38 so that the Meter display has the same
reading of the lag bath thermometer.
