HOW TO MODIFY IT:
NOTE:
PARAMETER
PV CALIB
Allows the user to calibrate the 0% and 100% of the measure system.
Allows the user to calibrate the 0% and 100% of the measure system.
The message "1 (channel) CAL 0%" is flashing with "CONNECT 0%".
(Asks the user to prepare the system for the 0% calibration). Set input
generator to deliver a signal corresponding to low scale (0%).
NOTE: For some thermocouples, the accuracy is inherently low. For
these thermocouples, the "CAL 0%" (low point) has been shifted to the
values listed below:
Thermocouple CAL 0%
o
PR20-40 1100 C = 2012
o
B 600 C = 1112
o
WW26 400 C = 752
Then press ENTER, calibration starts and "CAL 0%" is flashing. To end
"CAL 0%", press ENTER to validate. You can press SETUP at any time to
cancel the process.
Then the message "CAL 100%" flashing with "CONNECT 100% " asks the
user to prepare the recorder for the 100% calibration.
Set input generator to deliver a signal corresponding to full scale (100%).
Then press ENTER, the 100% calibration starts and "CAL 100%" is flashing.
To end "CAL 100%", press ENTER to validate. You can press
SETUP at any time to cancel the process.
If you do not cancel the calibration (0% or 100%), "END CAL" is displayed
for 3 seconds. Press SETUP to exit.
If you do not press SETUP, the message "COPY ?" is displayed after 3
seconds. Pressing ENTER will copy the calibration result on all similar
connected ranges. Press SETUP if you do not want the result to be copied
on the other similar connected ranges.
Instrument should be allowed to warm up for a period of
calibration
