Page 5: Operation
4) OPERATION Note: Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning. VFD-ACV & ACV functions Inputs are made through the test lead terminals. VFD-ACV function is to deal with VFD (Variable Frequency Device) signals. It, however, further pre-selects the most appropriate voltage ranges and thus the Hz trigger levels to best cope with most VFD-Voltage and VFD-Frequency applications. - Page 6 , DCA & DC+ACA Input is made through the clamp jaws for non-invasive current measurements. Defaults at ACA Function. Press SELECT button momentarily and release to select the subject functions in sequence. Note: (Application and removal of the Clamp-on meter) For non-invasive current measurements, press the jaw trigger and clamp the jaws around conductor(s) of only one single pole of a circuit for load current measurement.
- Page 7 Resistance & Continuity functions Inputs are made through the test lead terminals. Defaults at Resistance. Press SELECT button momentarily and release to select. Continuity Capacitance & Diode functions Inputs are made through the test lead terminals. Defaults at Capacitance.
- Page 8 Temperature function Defaults at C (Celsius) readings. Press SELECT button momentarily and release to select F (Fahrenheit) readings. Inputs are made through the test lead terminals. Be sure to insert the banana plug type-K temperature bead probe with correct polarities. You can also use a plug adapter ST306 (Optional purchase) with banana pins to a type-K socket to adapt other type-K standard mini-plug temperature probes.
- Page 9 Electric Field EF-Detection In Voltage or Current function, press the EF button momentarily and release to toggle to EF-Detection feature. The meter displays “E.F.” when it is ready. Signal strength is indicated as a series of bar-graph segments on the display together with variable beep tones.
- Page 10 Hold The hold feature freezes the display for later views. Press the HOLD button momentarily and release to toggle the hold feature. 5ms CREST-MAX capture mode Press CREST (HOLD) button for one second or more and release to activate CREST- MAX capture (Instantaneous Peak-Hold) mode to capture signal peaks of voltage or current in duration as short as 5ms.
