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.
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.
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.
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).
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.
