The company’s megohmmeters for insulation resistance measurements are designed for high-speed testing in automated systems. The model 1868A provides an output current to 80 mA for fast charging of capacitive components and devices. The model 1868D provides test voltages up to 5,000 V d.c. for testing products with high-voltage ratings. Both models contain similar features such as a resistance measurement range of 10 kohm to 1 Pohm, a current measurement range of 1 pA to 1 mA, and a resistance and currency accuracy of +/-2 percent. The instruments’ back-lit display is said to enable quick, easy setup and display of test results.
