IV. Operation Instructions
To access optimum precision for all L, C and R measurements
especially at the highest and the lowest ranges, please use the
alligator test leads (TL-21) or improvised test leads applying to the
measurement for OPEN and SHORT calibration (refer to page
15~17) to reduce the parasitic effect of the test fixture before going
forward the measurement.
To secure the accuracy in specification, please only connect DUT
(device under test) to measuring socket or use TL-21 (standard
accessory) or TL-22 (optional accessory) for measurement.
If use improvised test lead for measurement please prevent using
long wire which may have incorrect result.
1. Power ON/OFF
y
When power on, all symbols will display for 2 seconds.
y
In Auto Power off mode, APO will be shown on the display. It
will power off automatically, if without any key operation or
measurement for 5 min. Buzzer will beep three times to
remind auto power off is ready to activate and then “OFF”
display to power off.
