QuadTech 1868A-D Megohmmeters
The 1868 Megohmmeters (Models A&D) are precise, full-featured digital instruments with both resistance and current measurement modes. They are capable of measuring Insulation Resistance from 10k to 1P? at programmable DC test voltages between 10 and 1000V (1868A) or 50 and 5000V (1868D).
For charging high capacitive devices, the 1868A supplies a powerful charge current up to 80mA and the 1868D up to 18mA. Remote I/O, RS232 and IEEE-488.2 interfaces for remote control operation and communication with other instrumentation are standard on both models.
