Testers & Meters
Published: April 2010
1 AFCI/GFCI Circuit Tester > Ideal Industries’ AFCI/GFCI circuit tester tests AFCIs and GFCIs for proper operation and shared neutrals. It verifies wiring configuration. It is compact, fitting comfortably in a pocket. A 1-in. cord adapter, alligator clip adaptor and carrying case are available separately.
2 Multimeter > Amprobe Test Tools’ ACD-14 PLUS 600A clamp-on multimeter has a dual display that allows simultaneous reading of amperage and voltage. Narrow jaws allow access to tight measurement areas while still accommodating conductors up to 28 millimeters. It measures AC current to 600A, AC and DC voltage to 600V, capacitance to 3000 μF, resistance to 40MΩ, temperature (with Type-K thermocouple probe), and micro amps for testing flame sensors.
3 Time Domain Reflectometer > Megger’s CFL535F time domain reflectometer can be used on any cable consisting of at least two insulated metallic elements, one of which may be the sheath or shield of the cable. Dual inputs and large graphic display allow many comparative tests to be performed between cable pairs or stored traces. It has 15 trace memories, and the software allows transfer of the waveform data to a computer.
4 Sound Level Meter > EXAIR’s digital sound level meter measures and monitors the sound pressure level in a variety of industrial environments. The F/S response time button provides a choice of slow response measurements for comparatively stable noise measurement or fast for varying noise.
5 Clamp Meter > Hioki’s 3288-20 is a true RMS current clamp meter that is pocket-sized. It has a dual action jaw for flexible operation; DMM functions for AC and DC voltage, (600V), resistance and continuity. It has test leads that measure voltage and resistance and a test lead holder for convenient voltage measurement.
6 Tester Kit > Fluke Corp.’s electrical/HVAC combo test kit includes the Fluke 62 mini infrared thermometer (which offers quick and reliable surface temperature readings), the Fluke T+PRO voltage and continuity tester (which detects AC/DC and has a GFCI trip and continuity beeper), and the pocket-sized Fluke 1AC-II VoltAlert non-contact voltage detector (which tests for energized circuits) in a soft carrying case.
7 Tester > HD Electric Co.’s Quick-Check transformer and capacitor tester tests the primary and secondary sides of single- or three-phase transformer installations for short circuits prior to energizing in the field. It also tests capacitors and capacitor banks. It has built-in self-test, single button automatic testing, audible alarm confirms OK test, and is powered by a 9V alkaline battery.
8 Clamp Meter > Extech Instruments’ EX840 1,000A CAT IV clamp meter provides noncontact IR temperature measurements with a laser pointer, and the product’s functions include AC/DC voltage, resistance, capacitance, frequency, diode and continuity. It captures true RMS current and voltage measurements, and peak hold captures inrush currents and transients. It features a bright four-digit, 4,000 count backlit display and has as a 1.7-in. (43 mm) jaw opening for conductors up to 750 MCM or two 500 MCM.
9 Megohmmeter > AEMC’s 5,000V megohmmeter Model 6505 performs voltage, insulation, and capacitance measurements. Features include automatic calculation and presentation of the dielectric absorption ratio and polarization index. Capacitance of the sample and discharge voltage present at the test leads is displayed at the conclusion of the test.
