5 Operation • To enter Manual select mode, press the operating mode, press the • button. To manually select the button repeatedly. To enter Auto select mode, press and hold the cator is displayed. button until the indi- 5.3 Auto/Manual range mode In Auto range mode, the meter automatically selects the most appropriate measurement scale. In Manual range mode, the desired range (scale) is set manually. • To enter Manual range mode, press the press the • button.
5 Operation 5.5.2 Basic current measurements WARNING Do not measure the current on a circuit when the voltage increases to more than 600 V. This can cause damage to the instrument and can cause injury to persons. Note If the measured voltage is greater than 30 V DC or AC RMS, the is displayed. indicator When measuring current using the clamp jaws, only one conductor should be enclosed by the jaws—refer to Figure 5.1. Figure 5.1 Correct and incorrect setup 1. 2. 3. 4.
5 Operation 5.5.3 Extended functionality In addition to the basic voltage and current measurements, the meter can be set to different modes for extended functionality. 5.5.3.1 Selecting the mode The mode icons applicable for the selected measurement type are displayed in the lower part of the display. When a mode is enabled, the icon is framed. Figure 5.
5 Operation 5.5.3.3 In-rush current mode In In-rush current mode, the meter displays the highest current reading in the first 100 ms after the trigger point. In-rush current mode is available when measuring AC current in Manual select mode. 1. Use the navigation buttons to select and enable In-rush current mode. Note If the in-rush current under testing may be more than 100 A AC, manually set the range to 600 A/1000 A before activating the in-rush current, see section 5.
5 Operation 3. Press and hold the button to disable Min/Max/Avg mode. 5.5.3.7 Harmonic Distortion mode In Harmonic Distortion mode, the meter displays the distortion percentage value for the first 25 harmonics as well as the total harmonic distortion. Harmonic Distortion mode is available when measuring AC current or voltage in Manual select mode. The harmonic distortion is expressed as Hn = (RMS of an individual harmonic n )/(RMS of the fundamentals) × 100%. 1. 2.
5 Operation 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. 4. 5. Connect the probe leads in parallel to the part under test. Read the active power value on the display. • • If the value is displayed without a sign, the power is flowing from the power source to the load.

If normal, L1 flashes for about 3 seconds. Then L2 is displayed. Move the red test lead to the presumed phase line 2. One of the following results is displayed: • • • 123 indicates clockwise or forward rotation, which means that the presumed phase line 1 is ahead of the presumed phase line 2.
5 Operation 1. 2. 3. 4. 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 terminal. Touch the tips of the probe across the part under test. Read the capacitance value on the display. Note For very large capacitance values, it may take several minutes for the measurement to settle and the final reading to stabilize. 5.
