.

1.  Send the command MODE1 to the unit.
2.  Send the command CAL to the unit.
3.  The response will be ZERO VOLTS.
4.  Apply 0.0000 volts to the input.
5.  Send the command ZERO.
6.  The response will be FS=X.XXXX
7.  Apply approximately 10.0000 VDC to the input (this can vary a few mV but must be measured 

accurately).

8.  Send the command FS=X.XXXX (where X.XXXX is your meter reading).
9.  The response will be FN=-X.XXX.
10.  Apply approximately -10.000 VDC.  This can vary a few mV.
11.  Send the FN=-XX.XXX command where -XX.XXX represents the voltage applied.
12.  The unit will respond CAL COMPLETE.
13.  Send the command MODE0 to the unit.

1.  Send the command MODE1 to the unit.
2.  Connect a voltmeter to the Speed BNC Output.
3.  Send the CALDAC command.
4.  The response will be READ ZERO.
5.  User will read the meter and send the ZDAC=XX.XXX command where XX.XXX represents 

the voltage read.  This offset is immediately applied.

6.  The hardware will respond “ZERO OK?”
7.  If the meter reading is not zero the user must return to step 3.
8.  If the meter reading is within 3 mv of 0 the user responds “ZERO OK.”  
9.  The unit will respond “READ FS.”  
10. User will read the meter and send the FSDAC=XX.XXX command where XX.XXX 

represents the voltage read.  This gain is immediately applied.  

11.  The hardware will respond “FS OK?”  
12.  If the meter reading is not 9 volts ± 3 mv the user must return to step 8.  
13. If the meter reading is 9 volts ± 3 mv the user responds “FS OK.”  The unit will respond 

CAL COMP DAC.

14.  Send the command MODE0 to the unit via USB.

1.  Send the command MODE1 to the unit.
2.  Send the command CALS to the unit.
3.  The response will be FREQ=XXXXXX.XX.
4.  Apply a square wave of 50 kHz to 99 kHz to the input. (This can vary from 50 kHz to 99 

kHz but must be measured accurately).
