IET / Quadtech / GenRad 1864-1644 Positive Polarity Megohmmeter, 1864, 50 kOhm to 200 T Ohm, 10 to 1090 Vdc

IET / Quadtech / GenRad 1864-1644 Positive Polarity Megohmmeter, 50 kOhm to 200 T Ohm, 10 to 1090 Vdc

The GR / QuadTech / IET Labs 1864-1644 Megohmmeter is the choice for more demanding applications. The test voltage can be set to any value from 10 VDC to 109 VDC in one-volt steps and to 1090 VDC in 10-volt steps. The 1864-1644 can be set to common test voltages for various capacitors. The 1864-1644 can measure resistances from 50 kΩ to 200 TΩ (2 x 10¹⁴Ω). General Radio 1864-1644.

The 1864-1644 features “reverse polarity” to operate in the same way as a GR 1644-A, while maintaining the higher performance of the GR 1864's. Although the 1864-1644 and 1864 instruments are similar in appearance and accuracy, the polarity of the output voltage is inverted, making the 1864-1644 ideal for cable testing on submarines or a direct replacement for the GenRad 1644.
