Princeton applied research ratio computer model rc-10
Unfortunately, we were unable to power on the unit because we do not have an applicable power supply for it. The unit requires what appears to be a NEMA Type J female power cord/adapter. Please refer to the provided pictures for details. Because of this, no testing could be done with the unit. We did check the gears inside of the unit over for damage which they all seem to be in good physical condition. This unit also does not come with replacement charting paper or ink cartridge, which both need to be replaced before proper use. We looked online for specifications for the recorder but we could not find any. We have included what we could find out about the unit below:
* Channel 1 & 2 Input Model Number: 71500A
* Input Connections: 5-270 DIN (Both Channels)
* Base Dimensions: 19" x 7" x 9"
* Chart Speed: 1"/Hr to 2"/sec
* Power Requirements: 115/230 Volts, 50/60 Hz
