EDWARDS D35501000 (actually D355-01-000,) METER MODEL 507

WARNING: no longer sold. See 507 Meter mod to use Televac 2A gauge tube

    DIN cable pinout:
      1 - n.c. 
      2 - TC+ (sensor rd wire, 10mV out)
      3 - heater (sensor bn wire, 10mA)
      4 - TC- (sensor bk wire, gnd return)
      5 - heater (sensor gn wire, gnd return)
Tube output: 10mV DC full scale (below 1 milliTorr)
Heater drive: ~10mA ~0.8V (+5VDC with series resistor = 450 to 650 ohms adj)
NOTE: the heater is isolated from TC junction, so any modified version of Model 507 must use a floating panel meter, or a floating heater supply for the NON-isolated 4-wire gauge tubes "2A" or "KJL-1518"
