OPERATING INSTRUCTIONS
DIFFERENTIAL TEMPERATURE
1. When two K-Type thermocouples are attached to the meter,
the main display will show T1 temperature and the secondary
display will show T2 temperature. Insert one K-type thermo
couple into port T1 and another into port T2.
2. To measure the differential temperature press the "SEL" button
9
and the T1-T2 icon will be displayed. The main display will
show the differential temperature value.
3. Press the SEL button
9
again to exit differential temperature.
TEMPERATURE CALIBRATION
1. Remove leads from meter and slide the temperature probe input
switch
18
to close jacks and expose the K-Type thermocouple ports.
2. Insert K-type thermocouple into ports
17
(observe polarity
markings on thermocouple and meter), and rotate function
selector switch
2
to the Temperature setting.
3. Long press the MAX/MIN button
8
and the V+A/Inrush button
10
at the same time. The meter will beep, and the CAL icon will
appear on the secondary display and the main display will have the
temperature measurement.
NOTE: In T-CAL mode, the T1 and T2 channels can be selected for
calibration by pressing the SEL button
9
, and the °F and °C units
can be changed by a long press to the SEL button
9
.
4. Place the K-Type thermocouple in a known temperature system
(eg. ice water, boiling water, or other standard temperature
source) and allow to stabilize.
5. Utilize the RANGE button
7
to increase the measured value and
the REL/LPF button
11
to decrease the value. Once adjusted to
the correct value, the T-CAL icon will appear on the display and
it will remain on the screen to designate a user calibration.
NOTE: To clear calibration data, long-press the HOLD
6
button to
default to factory temperature calibration. The T-CAL icon will be
removed from the display.
6. To exit the calibration mode, long-press the MAX/MIN
8
button
and the
V+A/Inrush button
10
at the same time.
