    2. Panel Description 1. Transformer Jaw This is used to pick up current signal. To measure DC/AC current, conductor must be enclosed by the jaw. 2. Transformer Trigger This is used to open the jaw. 3. Function Selector Switch This is used to select the function user desired, such as DCA, ACA, DCV, ACV, Hz, Ohm and Continuity.
  • Page 6 updated. Press again, maximum value shall be displayed and updated. Zero function will be disabled if MAX/MIN is enabled. This button is not available in duty, hz, continuity, diode or capacitance function. 7. VΩRANGE Zero/Relative Button On voltage or ohm function, press this button to select manual range. On other functions, once this button is pressed, the current reading shall be set to zero and be used as a zero reference value for all other subsequent measurement.
