METERMAN Test Tools, represented in Australia by Fluke Australia , has released the AC71 clamp-style digital multimeters (DMM). The clamp meter offers the AutoTect feature and an automatic backlight.
The AutoTect feature automatically senses what type of measurement is being made when test leads are placed across a measurement point. With no knob to turn, the meter automatically senses what is being tested and displays the measured value along with the associated unit icon. AutoTect also employs a lower input impedance to help determine if voltage is leaking (ghost voltage) or if there is a hard connection. Any possible ghost voltage will be eliminated by the lower input impedance.
An automatic backlight sensor recognizes when ambient light is insufficient and turns on a bright blue backlight for easy viewing of the digital display. With one-button control, the AC71 measures ac current to 600A, ac volts to 750V, and dc volts to 1000V. In addition to the resistance and continuity beeper, the meter features Data Hold and is rated to CAT II 1000V.
