WARNING To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. The meter is intended only for indoor use. To avoid electrical shock hazard, observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard to the user. -

3) PRODUCT DESCRIPTION This user's manual uses only representative model(s) for illustrations. Please refer specification details for function availability to each model. 1) Transformer Clamp Jaws for AC current magnetic field pick up 2) Jaw marking lines for ACA (& thus Power) position error indication 3) Hand/Finger Barrier to indicate the limits of safe access to the jaws during... -

4) OPERATION AutoVA function Set the slide-switch function-selector to the position. ●With no input, the meter displays “Auto” 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 6 around only one single conductor of a circuit for load current measurement. Make sure the jaws are completely closed, or else it will introduce measurement errors. Enclosing more than one conductor of a circuit will result in differential current (like identifying leakage current) measurement.
- Page 7 Line-level Frequency function When ACV or ACA function is auto-selected or manual-selected, press Hz button momentarily toggles to Line-level Frequency function. Frequency trigger levels vary automatically with function ranges. Peak-rms mode Peak-rms compares and displays the maximum RMS value of surge voltage or current with durations as short as 65ms.
- Page 8 Notes on Displacement Power Factor & True Power Factor ●Introduction: Power is the rate of change of energy with respect to time (in terms of voltage V and current A). Instantaneous (real) power w = vi where v is the instantaneous voltage and i the instantaneous current.
- Page 9 ●PF (Total Power Factor) displays simultaneously in the secondary mini display. Denoting efficiency, absolute PF value is adopted. ●“A-lags” LCD annunciator turns on to indicate an inductive circuit, or Current A lags Voltage V (i.e., phase-shift angle θ is “+”). On the contrary, together with significant PF values, WITHOUT “A-lags”...

System (total) power kW is the summation of all three phase-to-neutral Total powers.
- Page 11 ●Measuring 3-Phase 3-Wire (3 3W) Power Parameters: In both un-balanced and balanced load cases, 3-Phase 3-Wire (3 3W) systems, measure the power components kW and kW separately as illustrated. System (total) power kW is the summation of the two measured power components. That is: Total = kW + kW...

Disabling Auto-Power-Off (APO) Press-and-hold the HOLD button while sliding the function-selector to a (designated) function-selector position. This disables the Auto-Power-Off feature of the functions on that particular function-selector position. The LCD displays “ ” & “ ” to confirm activation right after the HOLD button is released. Slide the function-selector to any other positions then resumes Auto-Power-Off feature. - Page 14 Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for periods of longer than 60 days, remove the batteries and store them separately Battery replacement The meter uses standard 1.5V AAA Size (NEDA 24A or IEC LR03) battery X 2 Loosen the 2 captive screws from the battery cover case.
