  • Page 7 1. Transformer Jaw This is used to pick up a current signal. To measure DC/AC current, a conductor must be enclosed by the jaws. 2. Transformer Trigger This is used to open the jaws. 3. Data Hold Button Press this button to hold the current reading in the LCD display. Press it again to release the HOLD function .
  • Page 8 12. Relative Button 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. The function can also be used to offset readings caused by the residual magnetism remaining in the core for DC current measurements.
