Press the SELECT button momentarily to select the subject functions.
Last selection will be saved as power up default for repeat measure-
ment convenience.
Using resistance, continuity OR Ns function in a live circuit will
produce false results & may damage the instrument. In many cases
the suspected component must be disconnected from the circuit
to obtain an accurate reading.
CAUTION :
TM
BeepLit Continuity
function is having improved convenience
for checking wiring connections & operation of switches. A continu-
ous beep tone together with flashing display backlight indicate a
complete wire. Such audible and visible indications improve
continuity readabilities in noisy working environments.
Conductance is the inverse of Resistance, that is S=1/
or
nS=1/G
. It virtually extends the Resistance measurements to the
order of Giga-Ohms for leakage measurements.

When entering the 200
range manually by
RANGE
button for high
precision low resistance measurement, this feature will prompt you
to short the inputs for temporary test lead resistance calibration on
this range.
The fastest way is to short the leads to auto-range to the 200
range,
then press the
RANGE
button momentarily. The display shows
“
Shrt
”. Keep shorting the leads for further 3 seconds until the
display shows zero. The lead resistance is then temporarily
compensated.
The compensation value stays until the next meter power reset, &
can be as high as 5
. If you need a compensation value that is
higher than that, Relative Zero mode is recommended
