Note: In the slot columns, the digit after the G is the channel number and the number immediately preceding
the X assigns the voltage value, e.g., G1,1X means “Calibrate Gain for channel 1, ±50 mV.”

After each calibration type
U2X
and check for a return of
U128
to confirm no errors.
Response codes and meanings applicable to calibration are as follows:
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
4.
After completing the gain calibration of all cards, type
EX
to end the calibration mode.
5.
Type
U2X
to confirm calibration mode is disabled. A return of
U000
confirms this.
Note: You can view the calibration constants by typing an entry similar to the following:
C#1X
QC?
…for slot #1
You can monitor the calibration voltage by typing an entry similar to the following:
*B
…to clear the buffer
C1,1X
…to addresses the channel, this example is for slot #1, channel 1
T1,1,0,0X;@X
… to trigger the acquisition (Trigger LED flashes); );
@X
starts acquisition
U13X
every entry of U13X results in an updated value of voltage in counts
Note that
@X
can be used to start or stop the acquisition.
