Model LC-4 Handheld Voltmeter (Cat. #5203)

M. C. Miller Model LC-4 Voltmeter

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 Charactersistics

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

Telescopic Ball Handle Extension (Cat. # 16281)

Ball Handle Extensions

Telescopic Cane Handle Extension (Cat. # 16282)

Cane Handle Extension

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.

External Shunt

External Shunt

Two shunts which plug directly into the 20 mV range of the LC-4 Meter are available:

Cat. #5803

0.001O/ 50A/ 1mV = 1A
(measure up to 20A on the 20mV range).

Cat. #5800

0.1O/ 2A/ 100mV= 1A
(measure up to 200mA on the 20mV range).


Spare Carrying Case (Cat. # 5406>

Spare Carrying Case for LC-4 Voltmeter

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.

Electrode Extension Adapter (Cat. # 5701)

Electrode Extension Adapter for LC-4 Voltmeter

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.
