Section 11: Calibration

Frequency calibration

Make the connections as shown below, then perform the following calibration steps (AC Cal
Step 17 and Step 18):
AC Cal Step 17: 1V @ 10Hz
1. Send the following command:
SEND dmm.func = dmm.AC_VOLTS
SEND dmm.range = 1
2. Source 1V @ 10Hz
3. Send the following command:
SEND dmm.calibration.ac(17,1) print("done")
AC Cal Step 18: 1V @ 1kHz
1. Source 1V @ 1kHz
2. Send the following command:
SEND dmm.calibration.ac(18,1000) print("done")

Save calibration

Program today's date, cal due date, SN, and save the calibration constants in EEPROM
(electrically erasable programmable read-only memory) by sending the following commands:
dmm.adjustment.date=os.time()
dmm.calibration.verifydate=dmm.adjustment.date
