Aborting A Calibration Process; Sample Adjustment Program - Fluke 8845A Calibration Manual

Aborting a Calibration Process

Aborting a calibration process while the Meter is attempting to
write new calibration constants to memory may corrupt the
calibration constants memory.
To abort a running calibration process, stop the program or issue a device clear command
over the remote interface. No constants are saved until the Meter receives a record
command.

Sample Adjustment Program

The example below shows an IEEE 488 program that uses some of the commands to
adjust the 1V ACV portion of the Meter. Note that the ACV linearity adjustment must be
followed with a gain adjustment. Print is an output command to the Meter. Input Line
reads a response from the Meter.
INIT PORT 0<CR>
CLEAR PORT 0<CR>
# Enable Calibration
PRINT @<address of meter>, "CAL:SEC:STAT OFF, FLLUKE448X"
# Zeros
### Calibrate AC Linearity Set input value to 1.19V@1200Hz
# V@1200Hz
PRINT @<address of meter>, "CAL:VAL ACLIN,1.19"
PRINT @<address of meter>, "CAL? ON"
INPUT LINE @<address of meter>, A$
### Calibrate AC Linearity Set input value to 0.8V@1200Hz
# 0.8V@1200Hz
PRINT @<address of meter>, "CAL:VAL ACLIN,0.8"
PRINT @<address of meter>, "CAL? ON"
INPUT LINE @<address of meter>, A$
### Calibrate AC Linearity Set input value to 0.4V@1200Hz
# 0.4V@1200Hz
PRINT @<address of meter>, "CAL:VAL ACLIN,0.4"
PRINT @<address of meter>, "CAL? ON"
INPUT LINE @<address of meter>, A$
### Calibrate AC Linearity Set input value to 0.05V@1200Hz
# 0.005V@1200Hz
PRINT @<address of meter>, "CAL:VAL ACLIN,0.005"
PRINT @<address of meter>, "CAL? ON"
INPUT LINE @<address of meter>, A$PRINT @<address of meter>, "CAL:VAL"
### ACV Gain for 1V
PRINT @<address of meter>, "CAL:VAL ZVAC,1"
PRINT @<address of meter>, "CAL? ON"
INPUT LINE @<address of meter>, A$
PRINT @<address of meter>, "CAL:VAL ZVACS,1"
PRINT @<address of meter>, "CAL? ON"
INPUT LINE @<address of meter>, A$
# Disable Calibration
PRINT @<address of meter>, "CAL:SEC:STAT ON, FLUKE884X"
