Indication
Maximum
250 volts RMS with < 1500 Vpk transient
Isolation Voltage
Voltage
Range: 0 volts AC to 115 volts AC; 0 volts DC to ±150 volts DC
Measurements
Accuracy: AC: ±1%, ±2 volts AC (45 Hz to 65 Hz); DC: ±1%, ±2 volts DC
High Voltage
AC voltage detected to 115 volts DC voltage detected to ±150 volts.
Detection
AC voltage 90 volts or DC voltage 100 volts causes high voltage warnings to show on the
display
Tone Injection
Approximately 1 kHz at an amplitude of 80 % of battery voltage. Variable frequency and
cadence. Tone characteristics change as cable condition changes to "normal-open" from any
other condition.
