AMP135.0 CALA# DLYSTP1 VAL0
Again the ramp must be terminated with the bus “GET” meassage when the external AC
calibration DVM indicates the correct voltage.
The CAL header is used with the headers VLT, CUR and PWR to calibrate the respective
measurement function. An A, B or C extension follows the headers to designate a specific
measurement channel. If the extension is omitted, the calibation coefficeints for all
measurement channels will be the same and will depend on only value for phase A. The
arguments is a numeric value that represents the expected measured value. It should be
equal to an external precision TRMS voltmeter, ammeter or power meter.
The following ASCII string will cause the current measurement for phase A to measure the
vallue indicated by a TRMS ammeter standard, 10.12 amps:
CAL CUR A 10.12
3.7.5.9.TO PROGRAM A REGISTER (REG)
The REG header is used to load the register specified by the following numeric data with the
preceding data. The numeric value is from 0 to 15. The PRG header is identical to the REG
header and is included to standardize other AC power controllers.
The following example will load a ramp program that will step the voltage from 10 to 115
volts with 1 volt/.5 sec steps at 400 Hz into register 0.

3.7.5.10.TO RECALL A REGISTER (REC)
The REC header is used to recall previously loaded data from a register identified by the
following register number (0 to 15).
The following example recalls and outputs the parameters stored in register 0 by an example in
paragraph 3.7.5.10.
REC0
The following example recalls the parameters in register 0 and outputs the parameters after the
IEEE-488 "GET" message.
