This clamp-on digital meter, from m r engineer, is suitable for measuring temperature, dc and ac volts, frequency auto ranging, resistance, continuity, diode test and ac current. The portable instrument can measure: temperature ranges from -20oc to 750oc with a resolution of 1oc with the use of a temperature probe; dc volts up to 1000 v with overload protection; ac volts having ranges of 200 v and 750 v with overload protection; auto ranging frequency to measure frequency in the range of 2 khz to 20 khz; and resistance from 2 k to 200 k, also useful for checking continuity and diode test. The ac current can be measured in the range of 20 a, 200 a and 600 a maximum. The instrument has a 3-1/2 digit lcd, polarity indication, over range display, zero automatic, and low battery indication. This low cost unit works on 9 v battery having dimension of 192 x 82 x 33 mm with weight of approximately 270 gm.
