This moving-coil type, double-scale, volt-ammeter was designed to give the automotive electrician an instrument of small size and reasonable price that would be dependably accurate and make all important tests. It is ideal for testing regulators, batteries under a load, cables, relays, and coil current.
The sturdy black bakelite case is small enough to slip into the coat pocket - and is equipped with a hanger for hooking over the car door or bumper, or any convenient projection on the test-bench.
Three terminals are provided marked: +, A, and V; and a pair of test leads with clips are supplied.
- Connection of the leads to the + and V terminals gives a precise volimeter with a scale 2” long, reading 0/18 volts. 90 scale divisions together with the needle-like pointer of the knife-edge type, makes readings to 1/l0-volt easy and accurate, while the full scale of 18 volts will test either 6 or 12 volt systems on passenger cars or trucks. Green colored blocks on volt scale aid in checking voltage regulators.
- Connection of the leads to the + and A terminals gives the user a precise ammeter with a red colored scale of 5-0-60 amperes divided into 1 amp. divisions - a high enough range fo measure the output of special generators, but with easy readings of low currents down to 44 amp., by pressing button. The 5 amp. reverse reading is provided for checking opening of cutout relay.
