Limit LED LED lights up red to indicate an
exceeded limit value
LED lights up green to indicate adher-
ence to the limit value
LED LED lights up red to indicate the pres-
ence of interference voltage (when
instrument is switched off),

with
20 s on-time and 1 measurement each
for a duration of 5 s
– With batteries (alkaline manganese):
900 measurements
– With rechargeable batteries
(2000 mAh):
850 measurements
Safety shutdown If supply voltage is too low, the instru-
ment is switched off, or cannot be
switched on.
When the rotary switch is set to the OFF
position, the instrument is completely
disconnected from the batteries (after
approximately 10 seconds).
