NetScan User’s Manual Calibration 6-11
1. If the calibration password has not been changed, enter K12345. If the password has been changed,
enter the K command and the current password. This enables the calibration mode.
2. Type U2X to verify calibration mode. U128 should appear, indicating the unit is in calibration mode.
3. Type H1X. The Trigger LED will flash, indicating that offset calibration is in progress for Channel 1.
4. Type U2X. U128 should appear, indicating the unit is in calibration mode and no errors have occurred.
Response codes and meanings applicable to calibration are as follow:
Response to U2X Indication for Calibration Mode
U128 No error
U129 Read Failure (EEPROM Error)
U130 Write Failure (EEPROM Error)
U132 Chksum Err (EEPROM Error)
U136 Cal Err (offset, gain, or temperature sensor out of range)
U144 Invalid password
U160 Invalid command
10. Repeat steps for each additional calibration channel, using the H command, channel number and X.
11. When offset calibration is complete for all cards, remove the shorting connectors.
12. Reinstall original card connectors as applicable.
You are now ready to perform gain calibration for the signal conditioning cards, as described in one or both
of the following two gain calibration sections. The first gain section is for low volts cards (including the
CSN14/TC/P card); while the second gain section applies to the high volts card, CSN14/HV/S.
