Continuity and Insulation Testing
- Live circuit warning LED:
Immediate illumination of a warning lamp if the circuit under test is live - Auto Discharge:
Allows fast and safe discharge of electrical energy stored in capacitive circuits following testing - Integral overload protection on internal continuity and insulation test circuitry
- Autoranging
- 500V DC test voltage for insulation tests
- 200mA short circuit current on continuity ranges
- Wiring connection check LED’s:
Immediate indication if wiring of circuit under test is correct - Overheat Protection:
Rapid detection of overheating of internal circuitry,display of warning signal to user and automatic halting of measurement - Supply Voltage Indication:
Can display supply voltage value in loop impedance mode - Low Current Loop Impedance Test:
Short duration low test current will prevent tripping of many passive RCDs - Auto Data Hold:
Retains displayed reading for set period following test - Phase Angle Selection:
Selection of test current from +ve or -ve half cycle of waveform can prevent tripping of polarized type RCDs
