1868 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 1PΩ 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. |
