"The C.A 6541 is a high-performance 50 V to 1 kV insulation tester, which tackles the most demanding site conditions and is ideal for qualitative insulation analysis. Insulation: up to 4TOhms (5 cal.) at 50 \/ 100 \/ 250 \/ 500 and 1000 Vdc. Automatic calculation of insulation quality ratios: DAR and PI. Programmable test period and plotting of the R(t) curve (automatic memorisation of 20 samples). Automatic indication of voltage before and after measurement: 1 â†' 1000 Vac\/dc. Resistance: 0.01 Ω â†' 400 kΩ. Continuity: 0.01 Ω â†' +40 Ω (audible beep and lead compensation). Automatic measurement capacity after each insulation measurement: 0.005 â†' 4.999 μF. Microprocessor-controlled. Giant LCD with digital display + bar graph. Backlit display. SMOOTH function (smoothing of values displayed). Insulation test voltages can be locked. Programmable alarms. Long battery life: 8 LR14 batteries (21000 insulation tests of 5 seconds each). Dimensions: 240 x 185 x 110 mm. Weight: 3.4 kg.Tester Type = Insulation & Continuity TesterMinimum Test Voltage = 50VMaximum Test Voltage = 1000VMaximum Insulation Resistance Measurement = 4TOhmsDisplay Type = LCDTest Current = 200mAMinimum Operating Temperature = -10°CMaximum Operating Temperature = +55°CPower Source = BatterySafety Category Level = CAT III"
