High performance and value priced, the Test Bench

Series offers more features for the dollar than other multimeters. In addition to measuring voltage and current,

the meters also measure capacitance, frequency and temperature, and include component test, diode test and logic indicator capabilities. See the chart below for

the meter that best fits your needs. A double injection molded case provides improved grip and protection for the meters.

Features and Benefits

■ Resistance measurement

■ Frequency measurement

■ Diode check

■ Audible continuity

■ All current ranges fused

■ Auto power off

■ Ruggedized case

■ CATIII 1000 V, (all models)

■ CATIV 600 V, (392 & 393)
