2.  Apply calibration voltage from the precision calibrator to the first channel of each CSN14/HV/S card

(see following table), and verify with a digital multimeter.  Requirements for both devices are specified
in Required Equipment.

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., G1,20X means “Calibrate Gain for channel 1, ±2.5 V.”

3.  After each calibration type 

 and check for a return of  

 to confirm no errors.

Response codes and meanings applicable to calibration are as follows:

No error

Read Failure (EEPROM Error)

Write Failure (EEPROM Error)

Chksum Err (EEPROM Error)

Cal Err (offset, gain, or temperature sensor out of range)

Invalid password

Invalid command

 

4.  After completing the gain calibration of all cards, type 

 to end the calibration mode.

5.  Type 

 to confirm calibration mode is disabled.  A return of 

 confirms this.

 Note: You can view the calibration constants by typing an entry similar to the following:

 

  

…for slot #1

 You can monitor the calibration voltage by typing an entry similar to the following:

 

…to clear the buffer

 

…to addresses the channel, this example is for slot #1, channel 1

 

… to trigger the acquisition (Trigger LED flashes); ); 

 starts acquisition

 

every entry of U13X results in an updated value of voltage in counts

 Note that 

can be used to start or stop the acquisition.
