The General Radio 1800-P3 Low-Frequency Multiplier was introduced in Catalog M (1951) and remained available through Catalog Q (1961).
The Type 1800-P3 is an accessory for the Type 1800-A voltmeter designed to increase the input voltage range to 1500 volts. The multiplier is not recommended for use above 100 kHz unless adjusted for use at a fixed frequency. Above 100 kHz the Type 1800-P2 multiplier is recommended.
The multiplier attaches to the 1800-A probe observing the connections displayed at the output of the multiplier.
Specifications
- Multiplier Ratio DC: 10:1 ±1%
- Multiplier Ratio AC: 10:1 ±0.5%
- Input Impedance: DC 10 MΩ; AC 10 MΩ parallel resistance,with 10 pF parallel capacitance
