Electrical Installation Tester
Operatio n
23
The Tester maintains a separate zero value for each continuity range and
loop impedance tests. A unique zero is stored for each lead combination in
each function that allows the zero mode. The annunciator indicates
when a zero value is stored for the selected lead combination. For each
continuity range, zeros are valid for both polarities.
To zero:
1. Turn the rotary dial to the
,
, or position.
2. For R
LO
, use to select 10 mA or 250 mA range. A separate zero
value is retained for each range.
3. Connect the mains line cord (or the test leads) to the Tester and the
zero adapter. You can zero two or three test leads in the R
LO
function.
4. Press and hold for 2 seconds to 6 seconds until the annunciator
and the offset value show in the primary display. The beeper sounds
with each completed zero value.
The Tester measures the lead resistance, stores the value, and
subtracts it from readings. The resistance value is retained when the
power is turned off. If the Tester is the same function with the same
test leads or mains cord, you do not need to repeat the zero operation.
