    4.5 Frequency measurement from the terminals: 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 frequency of the voltage signal is needed.

  • Page 14: Frequency Measurement With The Clamp

    4.6 Frequency measurement with the clamp: Switch the main function selector to“ ” 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: Button Operation

    4.7 Button Operation: Data Hold Function: At any time, the user can hold the present reading by press the “Hold” button and release the held data by press it again. Peak Hold Function: This meter is built with 1ms peak hold function at ACA, ACV, DCA and DCV ranges.
