True RMS RMS (Root-Mean-Square) is a term used to describe the effective or equivalent DC value of an AC signal. True RMS is the term which identifies a DMM that responds accurately to the effective RMS value regardless of the waveforms such as: square, sawtooth, triangle, pulse trains, spikes, as well as distorted waveforms with the presence of harmonics. - Page 6 AutoV (LoZ) mode AutoV automatically selects measurement function of DCV or ACV, based on their input levels via the test leads. The input also provides a low ramp-up impedance (LoZ) to drain ghost voltages*. ●With no input, the meter displays “- - - -” when it is ready. ●When a signal above the voltage threshold of 1V DC or AC up to the rated 1000V is present, the meter displays the voltage value in appropriate DC or AC, whichever larger in peak magnitude.
- Page 7 WARNING: AutoV mode input impedance increases abruptly from initial 2.1kΩ to a few hundred kΩ’s on high voltage hard signals. “LoZ” displays on the LCD to remind the users of being in such low impedance mode. Peak initial load current, while probing 1000VAC for example, can be up to 673mA (1000V x 1.414 / 2.1kΩ), decreasing abruptly to approx.

- Page 10 BeepLit Continuity function is having improved convenience for checking wiring connections and operation of switches. A continuous beep tone together with flashing display backlight indicate a complete wire. Such audible and visible indications improve continuity readabilities in noisy working environments. In Diode function, the normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to 0.900V.

Application notes for flame sensors: DCA function is useful for HVAC/R flame sensor applications. The 0.1A resolution can identify the minute current changes in flame detector applications.

Press SELECT button momentarily toggles between modes. Last selection will be saved as power up default for repeat measurement convenience.
- Page 15 CAUTION Proper Rotation detection relies on solid signal connection to all three test lead terminals simultaneously. Any single disconnection will lead to detection failure and may produce false indication. To verify signal connection and hence proper meter indication, swap any two connects (to the meter) to check for meter indication of reverse movement Using the Hi-sensitivity mode for Motors:...

Hold The hold feature freezes the display for later view. Press the HOLD button momentarily to toggle the hold feature. Relative Zero ( ) mode Relative Zero allows the user to offset the meter consecutive measurements with the displaying reading as the reference value. Practically all displaying readings can be set as relative reference value including MAX/MIN/AVG feature readings. -
