QuadTech introduces two megohmmeters for insulation resistance measurements, the models 1868A and 1868D. Both units, containing similar features, are designed for high speed testing in automated system applications. Model 1868A provides a high output current to 80 mA for fast charging of capacitive components and devices. Model 1868D provides high test voltages up to 5000 VDC for testing those products with high voltage ratings. Resistance measurement range is 10 kΩ to 1 PΩ. Current measurement range is 1 pA to 1 mA. Resistance and current accuracy is ± 2%.
