4) OPERATION CAUTION: Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning. DC Voltage and AC Voltage functions Inputs are made through the test lead terminals. Note: DC 400.0mV range is designed with 1000M... - Page 6 ACA & DCA Current clamp-on function Inputs are made through the clamp jaws for non-invasive ACA & DCA current measurements. CAUTION (Application and removal of the Clamp-on meter) Press the jaw trigger and clamp the jaws around only one single conductor of a circuit for load current measurement.
- Page 7 CAUTION Do not measure above rated frequency (1kHz @ < 50A; 100Hz @ < 800A). In measuring above rated frequency, the magnetic circuits may reach to a hazardous temperature Resistance, and Continuity functions Inputs are made through the test leads terminals. Slide-switch on defaults at . Press SELECT button momentarily to select Continuity function which is convenient for checking wiring connections and operation of switches.
- Page 8 shorted diode (defective). An OL indicates an open diode (defective). Reverse the test leads connections (reverse biased) across the diode. The digital display shows OL if the diode is good. Any other readings indicate the diode is resistive or shorted (defective).

button momentarily again to step through the ranges. Press and hold the button for 1 second or more to resume auto-ranging mode. Display Backlight (Model 162s only) Press the SELECT button for 1 second or more to toggle the display backlight on and off. - Page 10 Battery replacement The meter uses standard 1.5V AAA Size (NEDA 24G or IEC R03) battery X 2; or 1.5V AAA Size (NEDA 24A or IEC LR03) alkaline battery X 2. Loosen the 2 captive screws from the battery cover case. Lift the battery cover case. Replace the batteries.
