5.4 HOLD Mode 1. In Hold mode, the display freezes the last reading and continues to display this value. 2. Press the HOLD button to toggle between Normal and Hold modes. In Hold mode, the indicator is displayed. 5.4.1 Smart HOLD The meter will beep continuously and the display will flash if the measured signal is larger than the display reading (for the V.A.W. function). 5.5 Silent Mode In Silent mode, the alert beeper is disabled. Silent mode does not affect the continuity beeper. 1.
Figure 5.1 Correct and incorrect setup 1. 2. 3. 4. 5. 6. Ensure that the probe leads are disconnected from the meter. Set the function switch to the A position. To manually select AC, DC, or AC+DC measurement, press the MODE button repeatedly. Refer to section 5.2 Auto/Manual select mode. To manually select the measurement range (scale), press the RANGE button repeatedly. Refer to section 5.3 Auto/Manual range mode. Press the trigger to open the clamp jaws. Fully enclose one conductor—refer to Figure 5.1.
5.6.3.2 Peak Mode In Peak mode, the meter captures and displays the positive and negative peak values, and updates only when a higher/lower value is registered. Peak mode is available when measuring AC current or voltage in Manual select mode. Use the navigation buttons to select 1. and enable Peak mode. 2. Press the OK button to toggle between the display of Peak Max and Peak Min. In Peak Max mode, the indicator is displayed. In Peak Min mode, the indicator is displayed. 3.
5.6.3.4 DC Zero Mode The DC zero feature removes offset values and improves the accuracy for DC current measurements. DC Zero mode is available when measuring DC or AC+DC current in Manual select mode. 1. Ensure that there is no conductor in the clamp jaws. 2. Use the navigation buttons to select and enable DC Zero mode. 5.6.3.5 Frequency Mode In Frequency mode, the meter measures and displays the frequency. Frequency mode is available when measuring AC current or voltage in Manual select mode.
5.6.3.8 VFD Mode (low pass filter) The VFD mode eliminates high frequency noise in voltage measurements by means of a low‐pass filter. The VFD mode is designed for variable frequency drive (VFD) measurements. This mode is available for measurements of AC current or voltage. 1. Use the navigation buttons to select and activate the VFD mode 5.7 Non‐Contact Voltage Detector Note: Test on a known live circuit before testing on an unfamiliar circuit. 1. 2.
5.8 Power Measurements 5.8.1 Single Phase Power Measurements Set the function switch to the W position. Insert the black probe lead into the negative COM terminal and the red probe lead into the positive W terminal. 3. Press the trigger to open the clamp jaws. Fully enclose one conductor—refer to Figure 5.1. For optimum results, center the conductor in the jaws. Note: The + symbol on the jaw should be directed toward the power source 1. 2. 4. 5. 6. 7. 8.
5.8.2 Three‐Phase Power Measurements 5.8.2.1 Three‐Phase Three‐Wire Balanced/Unbalanced The power of a three‐phase three‐wire delta configuration is measured in two steps, in accordance with Figure 5.4. The total power is the sum of the two measurements: W = W1 + W2. Figure 5.4 Three‐phase three‐wire measurements 1. 2. 3. 4. 5. 6. Set the function switch to the W position. Ensure that the meter is set to active power measurement.
5.8.2.2 Three‐Phase Four‐Wire Balanced/Unbalanced The power of a three‐phase four‐wire configuration is measured in three steps, accordance with Figure 5.5. The total power is the sum of the three measurements: W = W1 + W2 + W3 Figure 5.5 Three‐phase four‐wire measurements 1. 2. 3. 4. 5. 6. Set the function switch to the W position. Ensure that the meter is set to active power measurement.
5.8.3 Phase Rotation With the meter set to Phase rotation mode, it is possible to determine the phase rotation for a three‐wire system. Note: The system frequency must be stable. Figure 5.6 Phase rotation Set the function switch to the W position. Enter Phase rotation mode by pressing the MODE button repeatedly until the indicator is displayed. 3. Connect the red test lead to the presumed phase line 1 and the black test lead to the presumed phase line 3. 4.
123 indicates clockwise or forward rotation, which means that the presumed phase line 1 is ahead of the presumed phase line 2. 321 indicates counterclockwise or reversed rotation, which means that the presumed phase line 2 is ahead of the presumed phase line 1. ‐ ‐ means that the meter is unable to determine the results. Lo V means that users possibly removed the test leads before completing the testing procedure. To repeat the test, press the OK button again. 5.
5.11 Continuity Test Warning: Do not do diode, resistance or continuity tests before you have removed the power from capacitors and other devices under test during a measurement. Injury to persons can occur. 1. 2. 3. 4. 5. Set the function switch to the position. Insert the black probe lead into the negative COM terminal and the red probe lead into the positive Ω terminal. Use the MODE button to select continuity measurement. The indicator will be displayed.
6. Maintenance 6.1 Cleaning and Storage Clean the meter with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for an extended period, remove the batteries and store them separately. 6.2 Battery Replacement 1. 2. 3. 4. To avoid electrical shock, disconnect the meter if connected to a circuit, remove the probe/thermocouple leads from the terminals, and set the function switch to the OFF position before attempting to replace the batteries.
