E3511 insulation tester ELECTRICAL Insulation Resistance Range: 100kΩ to 100GΩ Insulation Range Accuracy: ±1.5% of scale length Insulation Range Temperature Coefficient: <0.04% of scale length Voltage Range: 1000 volts AC or DC Voltage Range Accuracy: ±1.5% of scale length Test Voltages: 500V, 1kV, 2.5kV, 5kV DC Test Voltage Accuracy: ±5% at 10MΩ Break Point Current: 0.5mA nominal Short Circuit Current: 1.2mA nominal Ripple Voltage: <10V peak to peak (R<10MΩ) Capacitor Charging Time: 15 seconds nominal to charge a 2µF capacitor to 5kV Capacitor Discharge Time: 2 seconds nominal to discharge a 2µF capacitor from 5kV to 50V Hum Rejection: 2mA RMS on 5kV range Maximum Voltage on Measurement Terminals: 1kV across H and L terminals; 1kV across H and guard; 250V across L and guard Internal Battery: 12V, 3AH, NiMH Having both battery and mains operation and four selectable DC test voltages (500V, 1kV, 2.5kV & 5kV), this tester measures insulation resistance from 100kΩ to 100GΩ. The large, clear analogue scale also displays AC or DC voltage up to 1000V. Latching test switch allows hands free testing. With full over-voltage and over-current protection for measurements and 16 hours operation from rechargeable NiMH batteries, the E3511 comes complete in a rugged carry case. Standard accessories include locking 2m test leads with prods and clips.
