Battery Replacement - LEM PR200 Bedienungshandbuch

If necessary adjust the probe output voltage to zero as
described in section 3.2. Clamp the jaws of the probe
round the conductor ensuring a good contact between
the closing faces of the jaws.
Observe and take measurements as required. Positive
output indicates that the current flow is in the direction
shown by the arrow on the probe.
True r.m.s. readings can be obtained by using an
appropriate true r.m.s. reading multimeter.
Core eddy current heating is produced when
Irms x f > 400,000.

Use of the probe on uninsulated conductors is limited
to 300V r.m.s or d.c. and frequencies below 1kHz.
Safety in its use is the responsibility of the operator who
must be a suitably qualified or authorised person.
Do not use the probe if any part of the probe including
the lead and connector(s) appear to be damaged or if a
malfunction of the instrument is suspected.
When using the probe ensure that your fingers are
behind the protective barrier see Fig. 1 or Fig. 2.
Clean the case periodically by wiping it with a damp
cloth and detergent. Do not use abrasive cleaners or
solvents. Do not immerse the probe in liquids.
5. BATTERY REPLACEMENT
SAFETY WARNING
Before removing the battery cover,
make sure that the probe is remote
from any live electrical circuit.
The red LED will flash when the minimum operating
voltage is approached. Refer to Fig.1. use the following
procedure.
Unclamp the probe from the conductor, turn it off using
the On - Off switch and disconnect the output leads,
from external equipment. Loosen the captive screw
which secures the battery cover. Lift the cover through
30° and pull it clear of the probe body as shown in Fig
1or Fig 2. The battery is then accessible. Replace the
battery and re-fit the battery cover and fasten the screw.
Replacement with other than the specified type of
battery will invalidate the warranty. Fit only Type 9 V
PP3, Alkaline (MN 1604 ).
6. WARRANTY
Your LEM HEME current probe is guaranteed for one
year from the date of purchase against defective
material or workmanship. If the probe fails during the
warranty period, we shall at our discretion, repair or
replace it with a new or reconditioned unit provided we
are satisfied that the failure is due to defective material
or workmanship. To make a claim under warranty, the
probe should be returned to us, postage prepaid, with a
description of the defect. The use of a battery, other
than that specified invalidates this warranty.
