2-18. OVEN MONITOR OUTPUT

2-19. The OVEN MONITOR OUTPUT is an indicator of oven warm-up. At initial turn-on (warmup) the
oven monitor will go to approximately 1.5 volts BELOW the oven power supply voltage. After the
oven cuts back, the output will drop to approximately 3.5 volts (at 25°C). The output impedance of
this circuit is 10,000 ohms.

2-20. MATING CONNECTORS AND MOUNTING

2-21. The 10811A Oscillator requires a 15-pin printed circuit connector. The recommended connector is
the CINCH 250-15-30-210 (HP 1251-0160). The 10811A can be secured with two 6-32 screws,
1/4-inch long. Figure 2-3
