Voltmeter Characteristics:
  • High Voltage Isolation for Operator Safety : Tested to 1kV steady-state/15kV transient voltage levels (designed for higher voltage level isolation) – operator isolated from power supply
  • Non-Saturating : Voltmeter will not saturate on 5.7VDC and higher ranges with superimposed AC signals up to 120VAC (for readings up to approximately 50% of full scale at 60Hz) and/or inductive spikes up to 2kV appearing at the input terminals
  • Extensive Ranges : Various DC Ranges (40mV full scale to 570V full scale) plus 4V, 40V, 400V AC Ranges. All DC Ranges have <80ms response times for accurate On/Off pair readings during fast current interruption cycling (for example, 700ms ON / 300ms OFF).
Power Source:
  • Lithium-Polymer rechargeable battery
  • Interior battery charging port
  • Re-chargeable battery lasts approximately 8 hours with continuous usage
