calibration should be done before making any
measurements.
To enter calibration mode, simply press and hold
down the button for 2 seconds. A calibration
prompt will be displayed. There are two types of
calibration available. One is the open circuit
calibration. The other is the short circuit calibration.
To exit calibration mode, simply press and hold down
the button for 2 seconds again.
Open Calibration
Open calibration can be done when meter first enters
into calibration mode. If the input sockets or terminals
have nothing connected, the display should show
Figure 7. Also, “REL” indicator will be blinking on the
display. This is to prompt the user that the meter is
waiting for an action. At this point, open calibration
will be done when the button is pressed once.
Within a few seconds, the meter will return to normal
display and meter will be calibrated based on the test
frequency and settings selected prior to entering the
calibration mode.
