It should be used when you are unable to zero or span the instrument, when the slope and offset values are outside of the acceptable range, or when other more obvious reasons for problems have been eliminated.
  • Page 166 Teledyne API Model 200A NO Analyzer Instruction Manual, 02246, Rev. F1 Calculate the expected NORM PMT mV reading. For ranges up to 2000 ppb, multiply the expected span value by 2 to get the mV reading. For ranges 2001 to 20000 ppb, multiply the expected span value by .2 to get the mV reading.

    Teledyne API Model 200A NO Analyzer Instruction Manual, 02246, Rev. F1 9.2.6 Unstable Span Common causes are: Leak in pneumatic system. Light leak - check the sensor module with strong light. Instrument not fully warmed up. Sample lines or sample filter dirty - clean or replace.

    Teledyne API Model 200A NO Analyzer Instruction Manual, 02246, Rev. F1 9.2.7 Unstable Zero Common causes are: Leak in pneumatic system. Perform leak check, see Section 8.9. Miscalibration. See Table 7-1. Light leak - check the sensor module with strong light.

    Teledyne API Model 200A NO Analyzer Instruction Manual, 02246, Rev. F1 9.2.9 Inability to Zero If the ZERO button is not illuminated when attempting to zero, that means the reading is outside of the software gain ranges allowed. In an analog instrument it would be the equivalent to the zero pot hitting the rotation stop.

    Teledyne API Model 200A NO Analyzer Instruction Manual, 02246, Rev. F1 9.2.10 Non-Linear Response Common causes are: Leak in pneumatic system, see Section 8.9. High zero background - the PMT TEST function should be near 50 mV with zero gas.

    The most common requirement is the Ready to Send (RTS) signal must be at logic high (+5V to +15V) before the modem will transmit. The Teledyne API analyzer sets pin 8 (RTS) to 10 volts to enable modem transmission. Once the physical connection has been correctly established, it is necessary to establish the correct software settings in the modem.
  • Page 181 Teledyne API Model 200A NO Analyzer Instruction Manual, 02246, Rev. F1 To troubleshoot a modem connection first disconnect the RS-232 cable from the Analyzer and verify (use a DVM) that you are getting a signal on Pin 2 of the RS232 port on the Analyzer. The signal will be between -5V and -15V with respect to signal ground (pin 5).
