7.2.12 Data Calibration
Calibrate the voltage, resistance temperature detector, and reference junction compensation.
Calibration of the voltage
Calibration of the resistance temperature detector
Calibration of reference junction compensation
Example) When calibrating the voltage at Channel 1.
Enter the engineering mode (See the key operation
in page 69). Use the
△
key to display
"
", and press the
“
ENT
”
key. Use the
△
key to select "
", and press the
“
ENT
”
key.
Select the channel where an instrument for
calibration such as a mV generator is connected,
and then, press the
“
ENT
”
key.
Enter 0 mV. After 30 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
Enter 15 mV. After 10 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
Enter 25 mV. After 10 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
Enter 35 mV. After 10 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
Enter 55 mV. After 10 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
Enter 200 mV. After 10 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
Enter 1 V. After 10 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
Enter 5 V. After 10 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
Enter 10 V. After 10 seconds, make sure that the
ALM lamp unilluminates and press the
“
ENT
”
key.
If the calibration is correct, select "
" with
the
△
key, and if incorrect, select "
",
respectively. Then, press the
“
ENT
”
key.
[Note]
For calibration for voltage input, only one channel calibration is effective to all the channel.
