There are two functions under CAL Mode:
Open Cal will reduce the effects of contact resistors and test leads.
Short Cal will minimize the influence of distributed capacitors and resistors on testing
high impedance elements.
Enter CAL Mode
For convenience, OPEN CAL and SHORT CAL are designed to share a button. By pressing the
button, the meter will automatically choose either Open Cal or Close Cal.
Open Cal
First select frequency to Cal and keep test clip and test slot be open. Enter into CAL by pressing
the button, and a moment later the OPEN indicator will appear on secondary display
after the automatic measurement judging. If user decides to perform open Cal, another press of
should be done.
NOTE: “----” indicator on secondary display indicates that test terminal is out of open state and
Open Cal cannot be performed.

Short Cal
First choose test frequency to Cal and then insert a short plate to test slot. If SMD test tweezers
or test clip probes are used, the short plate should be connected to the ends of the probe in
order to account for the probes properties. Enter into Cal mode by pressing the button,
and a moment later the SHrT indicator will appear on secondary display after the automatic
measurement judging. If user decides to perform short Cal, press again the button.
NOTE: “----” indicator on secondary display indicates that test terminal is out of short state and
short Cal cannot be performed.
