Is the connecting cable Connect it. connected properly? Is the analyzer Connect it. input/output wiring connected properly? Is the sample gas piping connected...
Page 14: Start-Up
4-2 Start-up Perform the basic start-up operation as follows. O2 ANALYZER Display 1 ％ POWER Start-up operation RANGE Display 2 Turn power ON. ① When you turn ON the power to the analyzer, the POWER LED lights up and Display 1 starts the countdown.
Page 15: Stop Procedure
4-3 Stop Procedure Stop Procedure Turn OFF the power supply to the oxygen analyzer. There is no power switch on the analyzer, so turn off the Turn OFF the power external power supply. If operation is stopped for a short period such as 1 week or less, do not turn off the power. If operation is stopped for a longer period, once the sample gas is replaced by ambient air, then turn off the power.

Page 21 (2) Output Range Switching The output range switching method can be made from 2 methods: range switching by key operation, by Contact input, or by auto range switching. ①Range switching by key operation (Local range switching) By inputting 0 for CH026 and 0 for CH209, you can change output range 1 - 4 for CH020.
Page 22 ② Air, Zero 2 point calibration This analyzer doesn’t need to carry out zero point calibration standardly. How to zero point (0.0%O2point) calibration is shown in the following for the reference. (a) Input 1 to CH276 to set the calibration mode to air and zero 2 point calibration. (b) Send the Air to the Probe transmitter (sensor unit) at 1-3L/min ,and it stabilizes indication.
Page 23: Operation For When An Error Occurs
(e) Input to CH121 for span gas concentration. The concentration of span gas is to use the gas of the 90% in F.S. range. Send the span gas to the Probe transmitter (sensor unit) at 1-3L/min ,and it stabilizes indication. Air point is calibrated in a method to show in (e),(f) of ③. This procedure performs calibration.
Page 24: Applied Operations
4-6 Applied operations (1) Primary delay time setting With the data value input to CH016 (unit: seconds), primary delay can be applied to the concentration output signal. The setting range is 0 - 99 seconds. (2) WET/DRY The output of oxygen concentration when 0 is inputted to CH18 is WET output. When fuel to use is gas fuel, each element concentration (vol %) in the fuel is inputted to CH230 - 239, and 1 is inputted to CH018.
Page 25 (5) Current output adjustment ① Connect an ammeter to check OUT1+ and OUT1- on the analyzer terminal board. ② When CH027 is called up, the display shows "cAL 1". ③ When you press the key, 0 is displayed on display 1. Each time you press the key, display 1 can be switched to 0 and 100.
Page 26 (8) Contact output (RY1 – 4) setting The contact output contents are set using CH200 - 203, and the contact output movement settings are set using CH204 - 207. RY1 contact output functions are set at CH200, and the contact output operation settings are set using CH204.
Page 27: Maintenance
(9) RS232C Communication function setting The measurement status, error codes, range and measurement values can be transmitted. The formats include condition = measurement status (6 bytes), E = error code (2 bytes), RANGE = range No. (1 byte), ppm = measured value (maximum 11 bytes), CR + LF. The communication specifications (bit rate, data length, parity check, stop bit, etc.) are set by ENERGY SUPPORT CORP.
