Product Information:

• 1 year warranty
• High accuracy (2% rdg +1 digit)
• Compact, battery-powered insulation tester
• Three-range: low (25 V) to high (1,000 V)
• Discharge of circuit under test
• Backlit-illuminated
• AC voltage measurement
• Automatic discharge
• Addition of 500 V/2000MΩ model

• Discharge function
  The tester automatically discharge when you turn off the MEAS switch. The segment bar extends if there id any residual voltage in the circuit under test. You can make sure discharge id complete by checking that the segment bar disappears from the display. Under this condition, the tester is ready to enter voltage measurement mode.
• AC voltage measurement:
  The tester enters AC voltage measurement mode when you turn on the power (rotary) switch.
• Display:
  3 1/2-digit LCD; 4000 count maximum; 42-segment, logarithmic bar graph; over range input indicator "-" the OL symbol comes on if the measured value exceeds 2000 count (200.0 range).
• M ohm range selection:
  Fully automatic ranging.
• Range step-up:
  The tester shifts the range one step upward for input levels higher than 4000 count.
• Range step-down:
  The tester shifts the range one downward for input levels lower than 360 count.
• Dimensions (main unit):
  Approx. 120 (W) x 110 (H) x 60 (D) (mm)
• Weight:
  Approx. 500 g (including batteries)
