Model 200AU-NOy Option Manual Addendum
1. After confirming proper supply voltage, turn on the instrument power. If you are unfamiliar with
the M200AU with NOy Option, we recommend that you read the overview in Section 3 before
proceeding.
2. The power indicator light and display should immediately light, in addition the bypass pump
should start up. The M501Y requires about 30 minutes for the converter to come up to
temperature.
3. While the converter is coming up to temperature, the M200AU should be powered-up also. Follow
the instructions in Section 2 of the M200AU Manual to confirm proper operation of that
instrument. Note: It will take 30 minutes for the ozone generator to start up in the M200AU.
During that time the instrument will not respond to span gas.
4. After 30 min, the display on the Bypass Pump Chassis should read 315oC, indicating that the
converter is up to temperature.
5. Proceed to Section 4 of this manual to do a zero/span check.
