Press the RANGE (Test Voltage) button momentarily to select an intended test voltage of 50V, 100V, 250V, 500V or 1000V in sequence. Last selection will be saved as power up default for repeat measurement convenience.
  • Page 12 Lock-Test mode is recommended for continuous measurements. To apply, press the LOCK button momentarily to display the annunciator before pressing the TEST button momentarily. The LCD will show both & to indicate continuous measurement is active. Press again either button momentarily to release the Lock-Test mode.
  • Page 14 Smooth mode (Insulation Resistance function only) Smooth mode displays the running average of the last eight measured readings having changes within 300 counts in sequence. On the contrary, it displays directly, without smoothing, the measured reading that is beyond 300 counts in changes comparing to its former one.
