- Page 8 IV. Measuring Instruction: 4.1 ACA measurement: Switch the main function selector to A range. Open the clamp by pressing the jaw-opening handle and insert the cable to be measured into the jaw. Close the clamp and get the reading from the LCD panel. Note: Before this measurement, disconnect the test lead with the meter for safety.
- Page 9 4.2 ACV measurement: Switch the main function selector to V range. Connect red test lead to “+” terminal and black one to the “ COM “ terminal. Measure the voltage by touch the test lead tips to the test circuit where the value of voltage is needed. Read the result from the LCD panel.
- Page 10 4.3 DCV measurement: Switch the main function selector to V range. Connect red test lead to “+” terminal and black one to the “ COM “ terminal. Measure the voltage by touch the test lead tips to the test circuit where the value of voltage is needed. Read the result from the LCD panel.
- Page 11 4.4 Resistance measurement: Switch the main function to range. Connect red test lead to “+” terminal and black one to the “ COM ” terminal. Connect tip of the test leads to the points where the value of the resistance is needed. Read the result from the LCD panel.
- Page 12 4.5 Continuity Test: Switch the main function to range. Connect red test lead to “+” terminal and black one to the “ COM ” terminal. Connect tip of the test leads to the points where the conduction condition needed. If the resistance is under 40Ω, the beeper will sound continuously.
- Page 13 4.6 Frequency measurement from the terminals: Switch the main function to “ Hz ” range. Connect red test lead to “+” terminal and black one to the “ COM ” terminal. Connect tip of the test leads to the points where the value of the resistance is needed.
- Page 14 4.7 Frequency measurement with the clamp: Switch the main function selector to“ Hz ” range. Open the clamp by pressing the clamp-opening handle and insert the cable to be measured into the clamp. Close the clamp and get the reading form the LCD panel. Note: When doing frequency measurement, user should either use the terminal signal or clamp signal but not both.
- Page 15 V. Battery Changing: 1.When the battery voltage drop below proper operation range the symbol will appear on the LCD display and the battery need to changed. 2.Before changing the battery, switch the main dial to “OFF ” and disconnect test leads. Open the cover of the battery cabinet by a screwdriver.
- Page 16 * When take current measurement, keep the cable at the center of the clamp will get more accurate test result. * Repairs or servicing not covered in this manual should only by qualified personal.
