- Page 2 This high-sensitivity MirRONT A Multi tester is designed to me. a sure AC and DC voltages, DC current and Resistance with accuracy and ease. The large, single knob Range/Function control is easy to use and read. The Range Doubler switch (V•A/2 - V-n-A) effectively doubles the number of AC and DC scales available.
- Page 3 USING YOUR MULTITESTER Remove the back of the Multitester and install the batteries. Be careful to observe battery polarity. For most accurate readings, keep the meter laying flat on a non-metallic surface. Also, use a Range and Range Doubler switch setting that results in a reading in the upper I/3rd of the meter scale.
- Page 4 4. Read the voltage on the black DC scales. If the Range Doubler switch is in the V-A/2 position, be sure to divide the Range switch setting by 2 and read on the appropriate scale. 5. For voltages between 250 and 1000, set Range switch to 250&1000 and plug the red test lead into the 1000 Volt DC Only jack.
- Page 5 3. Now, connect the probe tips across the circuit or part under test. 4. Read the resistance on the green OHMS scale; use the proper multiplier to obtain the correct value (R "times" 1, 10, 100, 1000 or 10,000, depending on the position of the Range switch).
- Page 6 1. Plug the test leads into the correct jacks (Black into 0 COM and Red into EB V-n-A). 2. Set the Range and Voltage Doubler switches as required to obtain a meter reading in the upper ½ of the scale. 3.
