Page 6: Setup And Operation
Setup and Operation AC/DC Voltage Measurements CAUTION: Do not measure AC/DC voltages if a motor on the circuit is being switched ON or OFF. Large volt- age surges may occur that can damage the meter. 1. Set the rotary function switch to the V position. 2. - Page 7 Note: 0.2 A / 500 V fast-acting resettable fuse current inputs and Overload protection on mA, µA ranges. No replacement required. Resistance Measurements WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords.
- Page 8 Continuity Check WARNING: To avoid electric shock, never measure continuity on circuits or wires that have voltage on them. 1. Set the rotary function switch to the Ω position. 2. Press the MODE button to indicate on the display. 3. Touch the test probe tips to the circuit or wire you wish to check.
- Page 9 Data HOLD Button The data HOLD function allows the meter to “freeze” a measurement for later reference. 1.
