SECTION 4 OPERATION AND CALIBRATION

Important: These changes must be performed by a

qualified technician.

WARNING: Do not connect ac power to your meter until
you have completed all input and output connections.
Failure to do so may result in injury!

1. Wire the meter according to the wiring section. This

includes power, thermocouple and analog signal
connections.

2. Apply power to the meter and the display will show the

temperature of the probe.

The meter is shipped from the factory calibrated to the accuracy
as specified. No re-calibration is necessary. In the event that
there is a desire to check the calibration, the following
procedure is given.

4.1 EQUIPMENT REQUIRED

¥ Meter
¥ Extension grade thermocouple wire
¥ a small screwdriver
¥ a precision Thermocouple Calibrator

OR

4. Set the thermocouple calibrator to match the

thermocouple type of your meter. Adjust the
thermocouple calibrator to output the temperature
shown in the first line of column 2. Check to see that
the unit displays the temperature shown in column 3.
If not, adjust the zero potentiometer until it reads that
simulated value. For example, if the meter has a
"-JC2" in the model number, set the calibrator for

0.0¡C and the unit display should show -0.2¡C.

5. Adjust the thermocouple calibrator to output the

temperature shown in the second line of column 2.
Check to see that the unit displays the temperature
shown in column 2. If not, adjust the span pot until it
reads that simulated value. For example, if the meter
has a "-JC2" in the model number, set the calibrator for

170.0¡C and the meter display should show 170.0¡C.

6. After adjusting the pots, go back and verify both

temperature readings. Repeat steps 4 and 5 as
required.

4.2.2 Calibrating using a Millivolt Source

1. Disconnect the power from the meter. Remove the

front lens. Notice the the zero potentiometer is located
to the left of the display and the span potentiometer is
located to the right of the display.

Refer to Figure 4-1 for the location of the calibration
pots.

2. Connect the millivolt source to the MCJ Electronic Ice

Point or ice bath which in turn connects to the
thermocouple input connector P3 as shown in Figure
4-3. Connect the negative (red) thermocouple wire to
connector P3, Pin 1. Connect the positive
thermocouple wire to connector P3, Pin 2. Be sure to
observe polarity and use the correct thermocouple
wire (Type J wire for Type J meter).

3. Connect the power to the meter. Refer to the

appropriate model number in Table 4-2 for the proper
calibration points for your particular meter.

4. Adjust the millivolt source to output the millivolt value
shown on the first line of column 2. Check to see that the
meter displays the temperature indicated in column 3. If
not, adjust the zero potentiometer until it reads that
simulated value. For example, if the meter has a "-JC2"
in the model number, set the millivolt source for 0.0 and
the meter display should show 0¡C.

5. Adjust the millivolt source to output the millivolt value
shown on the second line of column 2. Check to see that
the meter displays that same value. If not adjust the span
pot until it reads that simulated value. For example, if the
meter has a "-JC1" in the model number, set the millivolt
source for 41.013 and the meter display should show
730¡C.

SECTION 6 GLOSSARY

COMMON MODE REJECTION (CMR)

- a measure of
the affect of a voltage on the indicated display. It is the
ratio of the common mode voltage to the measured
voltage due to a common mode voltage.

COMMON MODE VOLTAGE (CMV) - the average of
the voltage applied to both wires of a two wire or
differential input.

NORMAL MODE REJECTION (NMR) - a measure of
the rejection of unwanted signal due to a voltage
applied between the wires of a two wire or differential
input (shown as normal mode voltage). NMR is the
ratio of the normal mode voltage to the measured
voltage due to the normal mode voltage.

TEMPCO

- abbreviation for temperature coefficient. It
is the effect of changes in ambient temperature on a
particular parameter, such as zero or span settings.
