Table 3. Display
No. Description
R
H, RS and RE icons indicate the resistance type being displayed:
RH = Auxiliary electrode resistance
R
S = Probe resistance
R
E = Earth ground electrode resistance
Hazardous voltage. Voltage >30 V dc or ac peak might be
present.
ACTIVE icon indicates a measurement is in progress
Digits display measurement results and messages
ke icon indicates reading value is in kilohms (x1000)
>LIMIT icon indicates measurement value exceeds the set limit or
that auxiliary electrode resistance or probe resistance value
exceeds 199 ke
W icon flashes if measurement value exceeds set limit or leakage
voltage exceeds 20 V
LO-BAT icon indicates battery voltage is low
U icon indicates the displayed measurement is stray interference
voltage (above 20 V)
Interference Detection
The Tester automatically checks for interference voltage (noise) fault voltage
above 20 V. Interference above 20 V greatly diminishes the accuracy of
measurements. If the Tester detects interference voltage above 20 V, the
measurement automatically stops, the W icon flashes, the U icon displays, and
the value of the stray voltage displays.
Auto Shut-Off
The Tester has an auto shut-off feature that turns the device off after
10 minutes of inactivity. The Tester beeps to alert you that it is about to turn off.
To disable auto shut-off, simultaneously press and hold START and DISPLAY
while setting the rotary switch to any On position (3 pole, 2 pole or LIMIT). To
reset auto shut-off or to reset the Tester, turn off the Tester and then turn it on
again.
