Page 16: Precautions And Preparations For Measurement
4-2 PRECAUTIONS AND PREPARATIONS FOR MEASUREMENT (1) DO NOT attempt to take any voltage or current measurement that maybe exceed the maximum range of this instrument. (2) Be sure that battery is correctly placed in the case and connected to the battery snap. (3) Make certain the range selected is greater than circuit current or voltage prior to attempting a measurement. -
Page 17: Ac Voltage Measurements
(1) Connect red test lead to “ V Ω “terminal and black test lead to “ COM” terminal. (2) Set Range Switch to range. (3) Connect Test Prods of test leads IN PARALLEL to the circuit being measured. (4) Read the Voltage value on LCD. 4-4 AC Voltage Measurement ( True RMS Measurement ) WARNING Maximum Input Voltage of AC VOLT Range is 750VAC. -

Page 20: Resistance Measurement
4-9 Resistance Measurement WARNING Before taking any in-circuit resistance measurement, remove power from the circuit being tested and discharge all Capacitors. (1) Connect red test lead to “ V Ω “terminal and black test lead to “ COM” terminal. (2) Set Range Switch to Ω range. (3) Connect Test Lead to the Circuit being measured and read the resistance Value on LCD. - Page 21 If the input differs significantly from a sine wave, the reading is incorrect as a different conversion factor would relate the average value of the signal to its rms value (see table as below). Correct measurements of non- sinusoidal wave forms can be made directly with the true- RMS models.
