導通蜂鳴測試 (CONTINUITY BEEPER)
A CONTINUITY TEST BEEPER IS STANDARD. SO WHEN ARE CHECKING CIRCUITS FOR SHORTS OR OPENS, YOU DO NOT HAVE TO LOOK AT THE METER. THE BEEPER SOUNDS IF CONTINUITY IS PRESENT.
二極體 (Diode TEST)
- CIRCUIT VOLTAGE IS APPROX. DC 3V Max
電晶體 (TRANSISTOR hFE MEASUREMENT)
- 0 - 1000 hFE VALUES FO EITHER P.N.P. OR N.P.N. TRANSISTOR.
- * TEST CONDITION: BASE DC CURRENT APPROX. 10uA, VCE: APPROX. 2.8V.
