Measuring Voltage V �WARNING To avoid electrical shock, hazard or damage to meter, do not attempt to measurement that might exceed 1000 V DC or AC RMS. Do not apply more than 1000 V DC or AC RMS to the input terminals. Note - If the measured voltage is higher than 30 V DC or AC RMS, the display will show “Y” symbol.
Measuring Current I �CAT IV 600V, CAT III 1000V with respect to earth for the jaw. Tactile Barrier for hand guard. �Do not hold the meter across the Tactile Barrier. I OK I I I OK OK I+(-I)=0 - Don’t clamp on any conductor while the meter power on. - ACD-50NAV, ACD-51NAV or ACD-53NAV has only AC current measurement mode. - Torch lighting when clamping. �CAUTION Please do not measure current from clamp jaw when temperature probe is connected to meter.
AUTO SENSE mode: Display measurement result at AC only with RMS value or DC value, it depends on whichever is greater. AC mode: AC only with RMS value. DC mode: DC value. AC+DC mode: AC+DC RMS value. Note: • Select “ AC”, “ DC” or “ AC+DC” indicator then press the navigator key to enter the AC/DC/AC+DC mode. • Select “ AC”,” DC” or “ AC+DC” indicator then press the navigator key for more than 2 seconds to return to the AUTO SENSE mode. PEAK HOLD (AC mode only) 1.
In PEAK HOLD mode, the meter is activated to save the positive peak value and negative peak value. Positive peak value is displayed in PEAK MAX mode. Negative peak value is displayed in PEAK MIN mode. Inrush Current : (AC mode only) If the under testing inrush current could be bigger than 100A ac, please select the range to 600A/1000A in advance before activating inrush current. ” indicator on the display to enter Inrush Current In ACA mode, select “ mode.
DC A ZERO (For ACDC-52NAV, ACDC-54NAV Only) Remove the jaw out of the conductor. Press HOLD Key > 2 seconds to compensate the residual magnetism. HOLD> 2 Sec HOLD - DC A Zero is only available in Auto Sense, DC and AC+DC mode. Measuring Frequency (AC mode only) Select the “Hz” indicator then press the navigator key to enter/exit the frequency measurement mode. "Hz" ENTER MAX/MIN/AVG Select the “MAX MIN” indicator then press the navigator key to enter the MAX/MIN/AVG mode.
"MAXMIN" "MAXMIN" ENTER MAXMIN >2sec "MAXMIN" "MAXMIN" Note : • Press HOLD key in MAX MIN mode to make the meter stop updating the maximum and minimum value. When the HOLD mode is activated in MAX MIN mode, the HOLD mode must be deactivated before the MAX MIN mode. THD Measurement (AC mode only) Select the “THD” indicator then press the navigator key to enter the THD mode. THD-F=RMS of Harmonics ÷ RMS of fundamental ×100%.
Individual Harmonic Measurement (AC mode only) Select the “ “ indicator then press the navigator key to enter the individual harmonic mode. To quit from the individual harmonic mode, press the navigator key for more than 2 seconds. Hn=RMS of Individual Harmonic ÷ RMS of fundamental ×100%.
Measuring Active Power (W) / Power factor (PF) 1. Single Phase Power Measurement Step1. Set the rotary switch to the “W” position. Step2. Connect the Red test lead to the Line conductor, and the Black test lead to the Neutral conductor. Step3. Press the trigger to open the transformer jaws and clamp one conductor only, make sure that the jaw is firmly closed around the conductor. Step4. Using the Navigator key to choose the “W/PF” mode.
2.Three Phase Power Measurement A. 3 phase 3 wire balanced / unbalanced Step 1. Set the rotary switch to the “W” position Step 2. Using the Navigator key to choose the “W” mode. W=W1+W2 1 3 2 Wye or star Red Red Black Black B. 3 phase 4 wire balanced / unbalanced Step1. Set the rotary switch to the “W” position Step2. Using the Navigator key to choose the “W” mode.
Phase Rotation Line 1 Line 2 Line 3 Note : • Connect three phase of power source as shown above. • The test is only available while the system frequency is stable. Step 1. Set the rotary switch to the “W” position. Step 2. Using the Navigator key to choose the “ “ mode Step 3. Connect the Red test lead and Black test lead to any of the line conductor (e.g. Red test lead to the phase Line 1, and Black test lead phase Line 3).
c) When displayed “- - - - “ means it is unable to determine line phases. d) If it displays “LoU”, it is possible that you remove the test leads before the meter completing its testing procedures. Step 5. To repeat the test, using the Navigator key and choose the “ “ mode again. OHM Measurement �CAUTION To avoid possible damage to the Meter or to the equipment under test, disconnect circuit power and discharge all high-voltage capacitors before measuring resistance and diode.
