Pin 23 - RUN/HOLD
A logic 1 (or open circuit) on this pin enables the unit to perform continuous measurements. When this line is
taken low, the unit completes the measurement in progress and halts. A pulse of 300nS will initiate a further
measurement.
Pin 24 - 0 VOLTS
All signals are referenced to this pin. If it is inconvenient to use this pin as the common, the V
LO
terminal may
be used instead.
The mating connector for the BCD option is a 24-pin Male Amphenol 57 series connector, Valhalla Stock
#05-10248. When using these outputs with a Valhalla Model 1248 Dual-Limit Comparator, use the IDC-3
cable for making connections.
The BCD connector pin functions are summarized in Table 6-1.
