Zero Calibration
Calibration of voltage and current zero would improve the accuracy of the
instrument before usage.
Connect (short) the two Kelvin clips together and press and hold the
button. A message of “ZERO CAL…” is shown in LCD. Release the button when
the message disappears.
Regular calibration of zero would maintain the accuracy of the instruments.
