Mrk engineers manufactures hand held, battery operated digi tal clamp meter model dm 6055c. This has a 3½ digit lcd display of 13 mm height, designed with exclusive use of onechip micro computer lsi circuitry. The main features include measurement of dc or ac current on the inductive conductor, built in data hold function and peak hold function for measuring transient signal. Lcd display allows clear read out even at high ambient light level, and high internal impedance assures minimum measuring error. Other features are automatic zero adjustment in display and built in over input and low battery indications. The meter can measure ac and dc amps and volts, resistance, diode continuity, voltage range from 200 volt to 1000 v dc, 200 volt to 750 v ac, current 200 amps, 400 amps, 500 amps and temperature furors 40°c to 750°c.
