Thermocouple Calibration for CH1
Converting °F to °C
1) Calibrate the meter to suit the temperature sensor input.
Use K type thermocouple input for thermocouples.
Use RTD 385 for RTDs.
2) To convert °F to °C enter the calibration mode and set
[CAL] to [10X].
3) Set the offset [OFFS_R] to [–178] counts on the display.
4) Set the scale factor [SCAL_R] to [0.55555] on the display.
Ignore the decimal point on OFFSET settings

Enter the Calibration mode [CAL], set to [111] and fine tune the
thermocouple calibration over the required temperature range.
Fine Tune Calibration over Specific Temperature Range
Follow Steps 1 to 5 for setting channels 2 and 3, using the following settings:
CH2
:
Code 4
[11X] for K type
CAL
[122] to calibrate K type
Code 4
[1X0] to select specific TC
CAL
[112] to trim selected TC.
CH3
:
Code 5
[X21] for K type
CAL
[123] to calibrate K type
Code 5
[X2X] to select specific TC
CAL
[113] to trim selected TC.
For a detailed thermocouple calibration procedure, see Advanced Calibration
& On Demand Mode Supplement (NZ203).

Select Temperature Units
Enter the Calibration mode [CAL], set to [101]. If you want °F
set offset to 0 and scale factor to 1. If you want °C set offset to
–178 and scale factor to 0.55555.
Note, once the temperature units have been selected, the
temperature inputs to the meter must be in the same units.
Note, this is not a mandatory step, carry out only if required.

Note:
CHANNELS 5, 6, 7
Are not available thru the front panel controls. They
can only be setup via the serial port using Texmate’s Meter
Configuration Utility program, or accessed via a macro.
