9.1.3.4 Ozone Gen Power

This diagnostic manually turns the power off and on to the ozone generator. When the M200AU is powered up from a cold start the ozone generator is not immediately started. This is due to the fact that humid air may be present in the generator cartridge. Humid air can produce nitric acid aerosol which can permanently damage parts of the instrument down stream of the generator. Using this diagnostic, it is possible to turn on the generator before the warmup time has elapsed. If you turn the power on it will remain on after you exit the diagnostic.

9.1.3.5 Analog Out Step Test

The Step Test is used to test the functioning of the 4 DAC outputs on the V/F board. The test consists of stepping each analog output 0-20-40-60-80-100% of the output. If the analog outputs are set for 0-5V full scale the outputs would step 0-1-2-3-4-5 VDC. The stepping can be halted at any value by pressing the key under the percentage on the front panel. When the test is halted, square brackets are placed around the percentage value in the display. Pressing the key again resumes the test. This test is useful for testing the accuracy/linearity of the analog outputs.

9.1.3.6 DAC Calibration

The Digital to Analog Converters (DAC) are calibrated when the instrument is set up at the factory. Re-calibration is usually not necessary, but is provided here in case the V/F board needs to be replaced and re-calibrated. The procedure for doing the DAC Calibration routine is in the Troubleshooting Section 9.3.3.1.

9.1.3.7 RS-232 Port Test

This test is used to verify the operation of the RS-232 port. It outputs a 1 second burst of the ASCII letter 'w'. During the test it should be possible to detect the presence of the signal with a DVM on pin 2 or 3 (depending on the DTE/DCE switch setting) or by the flickering of the red test LED. A detailed procedure is given in the Troubleshooting Section 9.3.2.
