The values to be held are the ones just before start calibration mode or setting value. It is selectable. Indication of instantaneous values will not be held. Remote output holding: Output signal is held at the latest value or setting value by short-circuiting the remote output holding input terminals. Holding is maintained while the terminals are short-circuited. Indication of instantaneous values will not be held. Switch ranges : The switch ranges is available in manual, auto, and remote modes. Only preset switch method is effective. Manual: Allows range to switch by key operation. Auto: Allows range to switch from low to high range when 90%FS or more is available in the low range. Allows range to switch from high to low range when 80%FS or less is available in the low range. Remote: N o-voltage contact input (for measurable components) Allows range to switch via an external signal when remote range switch input is received. When the contact input terminals for each component are short-circuited, the first range is selected, and it is switched to the second range when the terminals are open. Range identification signal: The present measuring range is identified by a contact signal. The contact output terminals for each component are short-circuited when the first range is selected, and when the second range is selected, the terminals are open. Auto calibration: Auto calibration is carried out periodically at the preset cycle. W h e n a s t a n d a r d g a s c y l i n d e r fo r calibration and a solenoid valve for opening/closing the gas flow line are prepared externally by the customer, calibration will be carried out with the solenoid valve drive contacts for zero calibration and each span calibration turned on/off sequentially at the set auto calibration timing. Auto calibration cycle setting: Auto calibration cycle is set. 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: T he time for flowing each calibration gas in auto calibration is set. Settable within 60 to 900 seconds (in increments of 1 second) Auto calibration remote start: Auto calibration is carried out only once according to an external input signal. Calibration sequence is settable in the same way as the general auto calibration. Auto calibration is started by opening the auto calibration remote start input terminals after short-circuiting for 1.5 seconds or longer. Auto zero calibration: Auto zero calibration is carried out periodically at the preset cycle. This cycle is independent on “Auto calibradion” cycle. When zero calibration gas and solenoid valve for opening/closing the calibration gas flow line are prepared externally by the customer, zero calibration will be carried out with the solenoid valve drive contact for zero calibration turned on/off at the set auto zero calibration timing. Auto zero calibration cycle setting: Auto zero calibration cycle is set. Setting is variable within 1 to 99 hours (in increments of 1 hour) or Setting is variable within 1 to 40 days (in increments of 1 day) Gas flow time setting: T he timing for flowing zero gas in auto zero calibration is set. Settable 60 to 900 seconds (in increments of 1 second) High/Low limit alarm: A larm contact output turns on when measurement value reach to the preset high or low limit alarm value. Contacts close when the channel value of each channel becomes larger than the high alarm limit value or smaller than the low alarm limit value. Instrument error contact output: C ontacts close at occurrence of analyzer error No. 1, 3 or 10. Calibration error contact output: Contacts close at occurrence of manual or auto calibration error (any of errors No. 4 to 9). Auto calibration status contact outputs: Contacts close during auto calibration. Pump ON/OFF contact output: During measurement, this contact close. While calibration gas is flowing, this contact open. This contact is connected in power supply of pump, and stop the sample gas while calibration gas flowing. Average value reset: A ve r a g e va l u e a ft e r O 2 c o nve r s i o n is started under preset condition by opening the average value reset input terminals after short-circuiting for 1.5 seconds or longer. Reset is carried out by short-circuiting. Restart is carried out by opening. 3 ZKJ7 Auto calibration interlocking function: W hen these two products are lined up and installed, output the auto calibration synchronized signal to second product. Contact output during auto calibration: While auto calibration is carried out, this contact is closed. Auto calibration end contact output: Cont act is closed for 1.5 seconds after finishing to flow the gas of auto calibration.
