§ Very Low Resistance
For full accuracy when reading below 0.1 mO, use the
average of forward and reverse readings. Make the reverse
reading by holding the “forward-reverse” switch in the
“reverse” position. A minus (—) sign will appear in the
display when this switch is in the reverse position;
disregard this when calculating the average.
§ Sunshade
To aid in reading the digital display in bright sunlight, use
the prop on the lid to hold it tilted partially open as a
sunshade.
1. Using Duplex Clamp leads on a circuit breaker or
transformer.
2. Using Duplex Hand Spikes on a motor commutator.
