This terminal is also the COM terminal for resistance measurement, for 110.00Ω~110MΩ (2-wire testing). (5) Ω Terminal This is the positive input termial for resistance measurement, for 110.00Ω~110MΩ(2-wire testing).
- Page 11 (9) REL Button In REL mode, the LCD displays D , where =1,2,3,..., D is the last value before REL is pushed, and D is the current value. If REL is pushed again in REL mode, the meter displays the reference value. The meter returns to normal operation if REL is pressed and held for longer than one second.
