Page 10: Autova Tm Function
AutoVA Function Set the slide-switch function-selector to the position. • With no input, the meter displays “ ” when it is ready. • With no ACA current input via the jaws but a voltage signal above the nominal threshold of DC 2.4V or AC 30V (40Hz ~ 500Hz) up to the rated 600V is present on V-COM terminals, the meter displays the voltage value in appropriate DC or AC, whichever larger in peak magnitude. -
Page 11: Peak-Rms Mode
Peak-rms Mode Peak-rms compares and displays the maximum RMS value of surge voltage or current with durations as short as 65ms. When ACV or ACA function is auto- selected or manual-selected, press and hold Peak-rms button for one second or more toggles to this mode. The annunciators “P-” “Max” turn on. APO (Auto Power Off) feature is disabled automatically accordingly. -
Page 12: Hold Mode
In ACA function, activating the Hz function during significant measurements can get the most appropriate trigger level to avoid electrical noises in most cases. Activating the Hz function at AC 40.00A range (before making significant measurements) can get the lowest trigger level (highest sensitivity). HOLD Mode When any function is auto-selected or manual-selected, press HOLD... - Page 13 power factor, is no longer the only component constituting the overall power factor. Harmonics do increase apparent power and thus decrease the overall power factor. That is the Total Power Factor is actually affected by both phase-shift angle and harmonics, and is given by the expression: Total Power Factor (PF) = Real Power (W) / Apparent Power (VA) In order to improve overall system power factor, nowadays power-system engineer needs to address both phase-shift and harmonics problems.

Page 15: Kwhr (Kilo-Watt-Hour) Recording Function
Note: 1. Under proper measurement setups for load circuits, the W (real power) readings are always positive. Negative W readings indicate reversed clamp-on jaws direction or test leads polarities, or even incorrect voltage lines are being measured as in 3-phase measurement setups. Correct them for proper “A-lags-V”... - Page 16 Set the slide-switch function-selector to the “3~Bal • 1~” Power position.
