Micro-Ohmmeter Model 5600
Warning
•These safety warnings are provided to ensure the safety of personnel
and proper operation of the instrument.
•Do not attempt to perform any tests with this instrument until you have
read the instruction manual.
•Tests are to be carried out on non-live and de-energized circuits only!
•The micro-ohmmeter should never be used in an explosive
environment (this includes poorly ventilated battery rooms and
enclosures).
•Make sure the internal battery is fully charged prior to testing. If the
instrument has been unused for several months, recharge the battery.
•We recommend recharging the micro-ohmmeter every month to
ensure a full battery charge when used.
•Only install fuses which are direct replacements.
•If the case needs cleaning, do not use any alcohol or oil based
cleaners. Preferably use soapy water with a damp cloth or sponge.
International Electrical Symbols
This symbol signifies that the instrument is protected by double
or reinforced insulation. Use only specified replacement parts
when servicing the instrument.
This symbol signifies CAUTION! and requests that the user refer
to the user manual before using the instrument.
Risk of electric shock. The voltage at the parts marked with this
symbol may be dangerous.
Definition of Measurement Categories

Description
The Model 5600 performs reliable low resistance measurements with
test currents to 10A and resolution to one micro-ohm.
The front end of the Model 5600 employs a four-wire Kelvin
configuration, which eliminates test lead resistance for a
measurement accuracy of 0.25%. A reverse polarity switch
compensates for the effect of DC voltage interference on the accuracy
and permits reading averaging. A built-in circuit filters against AC
signals.

Micro-Ohmmeter Model 5600
The Micro-Ohmmeter Model 5600 is housed in a sealed field case.
Power is supplied by a long-life NiCad battery with a built-in recharger
(110/220V). The large, easy-to-read LCD is 18mm high; it displays the
value of resistance, and indicates overrange and reversed connection of
measurement leads.
Four LEDs on the front panel indicate measurement faults (open circuit,
blown fuse, etc.); thermal protection; low battery and battery recharging.
For operator safety and instrument protection, the micro-ohmmeter is
fuse protected at the inputs. Two fuses, accessible on the front panel,
protect against stored energy in inductive loads.
Enhanced internal circuitry protects against possible inductive kickback
when the current is shut off. A built-in thermal switch protects the micro-
ohmmeter against overheating on the 10A range when in continuous
use.

Micro-Ohmmeter Model 5600
Disassembly
Before replacing the internal batteries or changing the power supply
voltage rating, the chassis must first be removed. Use the hex key to
unscrew the six fastening screws from the chassis, which are located on
the bottom of the case.
Pull out the chassis. Do not forget to unplug the two leads that connect
the power supply board in the bottom of the case to the boards, which
are mounted in the chassis. Be sure to note the polarity when
reconnecting the leads.
Detachable Cover
The cover hinges are fitted with spring-loaded clips, which allow the
cover to be removed. To detach the cover from the Model 5600, open
the lid to a horizontal position and apply downward pressure to the hinge
side of the cover while gripping it firmly (see Fig. 2).
To re-attach the cover, position the cover in a horizontal position and fit
the hinges into the respective housing. Apply strong rear-to-front
pressure to the cover until it snaps into place.

AC Power Selection
The Model 5600 may be recharged by 110V or 220VAC (47 to 450Hz).
The instrument includes a 110V supply cord, which provides the
charging voltage for the rechargeable battery. Verify that “110V” appears
on the indicator located below the line cord indicator socket on the front
panel; this will permit recharging with the 110V supply cord.
To change the charging voltage, disassemble the unit as previously
noted. Move the switch on the power supply board to the “220V” position
(see Fig. 3). A 220V supply cord (not supplied) is required for 220V
operation. Be sure to change the indicator on the front panel to the
“220V” position by removing the two screws that secure it and turning the
indicator over.
