Accuracy: ±2% of full scale when calibrated and operated at the same constant
temperature and pressure.*
±5% of full scale over the operating temperature range once tempera-
ture equilibrium is reached.*
* Additional 0.04 ppm on 0-1 ppm range, generated by internal scrub-
ber (which is necessary to maintain these specifications).
Response Time: 90 % of final reading in less than 61 seconds at 25 °C
Operating Temperature:0-50°C (32
-122 °F)
Analog Signal Outputs: For percent of full scale indication:
one 0–1 V dc non-isolated signal
one 4–20 mA dc isolated signal
For range identification:
one 0–1 V dc non-isolated signal
one 4–20 mA dc isolated signal
Digital Data Lines: One RS-232C serial interface for 2-way communications
with separate host computer—for remote monitoring and
control of all functions.
Alarms: Five user-programmable absolute-reading alarm setpoints,
with Form C, SPDT relays (3A resistive).
