RANGE CAT CAT + _ hc7f.eps Diode Test (G) RANGE CAT + _ _ Forward Bias Single Beep RANGE CAT CAT + Reverse Bias _ RANGE CAT CAT + Shorted Open and Good Diode Good Diode Bad Diode _ RANGE CAT CAT + Bad Diode hc5f.eps Continuity Test ( R ) RANGE CAT CAT + _ RANGE CAT CAT + _ hc8f.eps If continuity exists (resistance < 210 W for Models 21/75 and <270 W for Models 23/77), the beeper sounds continuously. The meter beeps twice if it is in Touch Holda mode. Current(?A) W Warning To avoid injury, do not attempt a current measurement if the open circuit voltage exceeds the rated voltage of the meter. To avoid blowing an input fuse, use the 10 A jack until you are sure that the current is less than 300 mA. Turn off power to the circuit. Break the circuit. (For circuits of more than 10 amps, use a current clamp.) Put the meter in series with the circuit as shown and turn power on. 1 2 RANGE _ CAT CAT + + 4 3 A hc10f.eps Probe Holder hc14f.eps Maintenance W Warning To avoid electric shock, remove the test leads before opening the case, and close the case before using the meter. To prevent fire and possible arc- flash, use fuses with ratings shown on the back of the meter. Caution To avoid contamination or static damage, do not touch the circuit board without proper static protection.
