The shortcut is to short the test leads in auto-ranging resistance
mode until the meter enters the lowest 50
W
range automatically,
press the
RANGE
button momentarily to get the "Shrt" prompt,
then wait about 3 more seconds until the display shows zero.
Note:
The calibration stays until you change ranges, functions, or
go back to auto-ranging mode.
Default at

*Note:
When measuring a 3-phase system, special attention should
be taken to the phase-to-phase voltage which is significantly higher
than the phase-to-earth voltage. To avoid exceeding the voltage
rating of the protection fuse(s) accidentally, always consider the
phase-to-phase voltage as the working voltage for the protection
fuse(s).

Default at

. Press
SELECT
button momentarily to select
Continuity function that is convenient for checking wiring
connections and operation of switches. A continuous beep tone
indicates a complete wire.

continuity function in a live
circuit will produce false
results and may damage the
instrument. In many cases the
suspected component must
be disconnected from the
circuit to obtain an accurate
reading.
CAUTION
When entering the 50
W
range
manually
by
RANGE
button for high
precision low resistance measurement, this feature will prompt you
to short the inputs for calibration. The display shows "Shrt". Simply
short the leads for about 3 seconds until the display shows zero,
then the resistance in the leads and in the internal protection
circuitry of the meter is compensated automatically. The compen-
sation value can be as much as 5
W
. If you need a compensation
value that is higher than that, Relative mode is recommended.
