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
Cat. IV: For measurements performed at the primary electrical supply
(<1000V) such as on primary overcurrent protection devices,
ripple control units, or meters.
Cat. III: For measurements performed in the building installation at the
distribution level such as on hardwired equipment in fixed
installation and circuit breakers.
Cat. II: For measurements performed on circuits directly connected to
the electrical distribution system. Examples are measurements
on household appliances or portable tools.

Receiving Your Shipment
Upon receiving your shipment, be sure that the contents are consistent
with the packing list. Notify your distributor of any missing items. If the
equipment appears to be damaged, file a claim immediately with the
carrier and notify your distributor with a detailed description of any
damage. Save the damaged packing container to substantiate your claim.
Packaging
The Model 5600 Micro-Ohmmeter (Cat. #1431.01) is supplied with a

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 microohmmeter against overheating on the 10A range when in continuous
use.
Electrical Specifications
Specifications are given for an ambient temperature of 23°C ± 3°, relative
humidity of 40 to 60% and a supply voltage of 6V ± 0.1V.
