9.1.3Optional Functions
Remote Output Holding:
Output signal is held at the last value or preset value by a voltage input to the remote output holding input terminals. Holding is maintained while the voltage is input to the terminals. Indication of instantaneous values are not held.
Range Identification Signal:
The present measuring range is identified by a contact position.The contact output terminals close for each component when the first range is selected, and open when the second range is selected.
Auto Calibration:
Auto calibration is carried out periodically at the preset cycle. When a standard gas cylinder for calibration and a solenoid valve for opening/closing the gas flow line are installed externally by the customer, calibration will be carried out using the solenoid valve drive contacts for zero and span calibration and will be cycled on/off sequentially at the set auto calibration timing.
Auto Cal Cycle Setting: Auto calibration cycle is user defined. Setting is variable within 1 to 99 hours (in increments of 1 hour) or 1 to 40 days (in increments of 1 day).
Gas Flow Time Setting: The time for flowing each calibration gas in auto calibration is user defined and settable between 60 to 900 seconds (in increments of 1 second).
Auto Cal Remote Start: Auto calibration starts by opening the auto cal remote start input terminal after short
