Data Sheet Handheld Digital Multimeters Test Bench® Series High Quality, Ruggedized, Multifunctional 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 Features ■ 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) 392 & 393 True RMS Ranging DCV Accuracy AC/DC Voltage and Current Display Digits, Count Bar Graph Capacitance Measurement Transistor Test Temperature Probe Logic Probe Relative Mode Min/Max Hold Peak Hold Data Hold USB √ Auto/Manual 0.08% √ 60000, 4 5/6 √ √ √ √ √ √ √ 393 only 391A √ Manual 0.05% √ 20000, 4 1/2 √ √ - 390A 389A 388B Auto/Manual 0.1% √ 4000, 3 3/4 √ √ √ √ √ √ √ √ Auto/Manual 0.25% √ 4000, 3 3/4 √ √ √ √ √ √ - Manual 0.5% √ 4000, 3 3/4 √ √ √ - Specifications 392 & 393 391A 390A 389A 388B Volts True RMS reading True RMS reading - - - 600 mV, 6 V, 60V, 600 V, 1000 V 200 mV, 2 V, 20 V, 200 V, 1,000 V DC Ranges 400 mv, 4 V, 40 V, 400 V, 1000 V AC Ranges 600 mV, 6 V, 60V, 600 V, 750 V 200 mV, 2 V, 20 V, 200 V, 750 V 400 mv, 4 V, 40 V, 400 V, 750 V Resolution 0.01 mV, 0.1 mV, 1 mV, 10 mV, 100 mV 10 µV, 100 mV, 1 mV 10 mV, 100 mV 100 µV, 1 mV, 10 mV, 100 mV, 1 V Basic DC Accuracy ±(0.08% rdg + 5 dgt) ±(0.05% + 3 dgt) Basic AC Accuracy ±(1.5% rdg + 20 dgt) 500 Hz -1 kHz ±(2% + 10 dgt) 500 Hz - 2 kHz Overload Protection 1000 VDC or 750 VAC rms 1200 VDC or AC rms 500 VDC/AC rms 15 sec on 200 mV range 1100 VDC or AC rms 1000 VDC or peak AC 1200 VDC or AC rms 500 VDC/AC rms 15 sec on 200 mV range Input Impedance 10 MΩ, 11 MΩ on 6 V range 10 MΩ 400 mV: >100 MΩ, 4V: 10 MΩ 40 V - 1000 V: 9.1 MΩ 10 MΩ Technical data subject to change © B&K Precision Corp. 2017 ±(0.1% rdg + 2 dgt) ±(0.25% rdg + 2 dgt) ±(1.5% rdg +5 dgt) 500 Hz - 1 kHz www.bkprecision.com ±(0.5% rdg + 1 dgt) ±(1.5% rdg +3 dgt) 500 Hz - 1 kHz High Performance DMM Test Bench® Series Specifications Current Ranges Resolution DC Accuracy AC Accuracy Input Protection Max.
