Analog Multitester

AU-31

INTRODUCTION This is a tester developed, in a basic policy of radical design and functions, for use in measurement in a small capacity electric circuit that is equipped with functions equal to those of a digital tester. The tester features adoption of a switching method of automatic-range switching (when measuring voltages & resistances), automatic-polarity selection type with no pointer needle reverse-swinging at minus input, high input impedance type, series-connected capacitor input type, and 0-ohm adjustment non-required, thus providing an easy-to-use analog multifunction.

FEATURES
Adoption of genuine full-automatic ranging eliminates the need to switch in
measuring voltage and resistance, and enables optimum range to automatically be set.
For direct voltage and direct current, polarities of + - can be automatically
measured, and LED lights at the - (minus) input.
For both DC and DC currents, high input impedance of 10Mohms at voltage
measurement eliminates measuring loss.
For DC/AC superposed circuit, AC component only can be measured with
DC component eliminated, when measuring AC current.
Differently from a conventional tester, 0-ohm adjustment is not required when
measuring resistance.
Consumption of internal batteries can be recognized without difficulties.
Closing a cover ( lid ) automatically switches off the power.
