DESCRIPTION

The LEMC model CP-2B prover counter may be used for proving, counting or totalizing applications. Completely self contained, it requires no accessory equipment other than connection to a transducer, such as a photo pulser, turbine meter, tachometer, magnetic pickup or other device which delivers a pulse or sine wave output.

The LEMC model CP-2B accepts high-speed pulses using either a balanced input for inherent noise reduction or an unbalanced input. These pulses are processed using a high sensitivity input amplifier and displayed using high-speed integrated circuits and a long life crystal display. A sensitivity adjustment (VR1) is included in the unit to remove unwanted noise. For proving, internal gating circuits are provided to automatically startand stop the counter. Counts may be accumulated if desired and all gate and reset functions may be controlled remotely.

The LEMC model CP-2B prover counter will operate from either a 120 volt AC power or a 12 VDC power source and provide a regulated voltage for operation of a photo pulser. The use of all solid state circuitry provides inherent reliability and compactness.
