LC-4 Handheld Voltmeter
Pick up a Model LC-4 and have these features in the palm of your hand:
- DC volts for IR drop, potential & rectifier readings
- AC volts for potential & rectifier readings
- Ohms for continuity & resistance testing
- Selectable input resistance display "freeze" for instant off & coordinated tests
- Optional plug-in shunt for current readings
- Heavy duty carrying case
General
Model LC-4 is the first hand-held voltmeter to include a number of special
features which facilitate corrosion and cathodic protection
testing on underground structures. It is designed for field
testing under almost any environmental conditions. Sealed Mil
Spec. switches, sealed windows, a gasketed case and a printed
circuit board with baked-on moisture and fungus resistant coating
on both sides make this possible.
The large (0.5") display characters are easy to read under both high and low
lighting conditions and function over a wide temperature range
with very little drain on the battery.
The LC-4 is recommended for potential surveys, side drain measurements,
surface potential surveys, IR drop measurements, checking both the
AC and DC circuits of rectifiers, checking for stray or hazardous
AC potentials, and checking galvanic anodes. DC current
measurements require the use of an optional plug-in shunt (0-20
Amp).
The selectable input resistance feature permits detection of
high resistance in the external circuit and elimination of
resulting errors in virtually all cases.
The push-to-hold-reading button freezes the display at any
desired time, which makes the meter usable in many areas having
varying stray currents. It is also useful when conducting
instant-off and coordinated tests.

Accessories for LC Series Voltmeters
Spare Carrying Case
Made of heavy, water resistant simulated leather, this carrying case leaves
your hands free to perform tests. A quick opening snap permits
ready access to the instrument, and a belt loop is included
with a snap fastener.
Cat. #5406
Price $60.00
Electrode Extension Adapter
(shown with optional
electrode and 30" Intermediate Extension, Cat.#16203,
attached.)
Designed to save
effort (and your back) as well as to protect you from snakes
and poison ivy, the MCM electrode extension adapter firmly
mates with the base of the meter by the use of Velcro® pads.
The base has a threaded socket which connects to either input
terminal by means of a test lead pigtail with a banana plug.
Any MCM intermediate electrode extension can be screwed into
the socket.
Cat. #5701
Price $50.00
Telescoping Extensions
Ball Handle Extension
Cat. #16281
Cane Handle Extension
Cat. #16282
Designed to access those
hard to reach places, the telescoping
extension adjusts to the user's height and
the twist cam lock feature secures the cane at
any length between 32 and 48 inches.Any
MCM electrode can be attached to fit the user's
application (electrodes are not
included)
