Make sure the M501-TRS is turned off and no AC power is being
supplied to the heater before proceeding.
• Check the resistance across the heater coil. It should be
approximately 16.5 ohms.
• Check the wiring between the heater and the power supply.
• Check to make sure the M501-TRS cooling fan is operating properly
and that the instrument is properly ventilated. Poor ventilation can
cause the M501-TRS' thermal switch to turn off the converter to
prevent overheating.
• Check to make sure that the thermal switch and heater control relay
are operating properly.
In addition to the causes listed in the Excessive noise section in the T101 Manual (PN
07266), an excessively noisy TRS measurement can be caused by hysteresis or
fluctuations in the temperature of the TRS converter oven in the M501-TRS. If this is
the case, perform the autotune procedure described in Section 7.4. of this addendum.
In addition to the information contained in the Subsystem Checkout section in the T101
Manual - PN 07266, the following diagnostic procedures are useful for troubleshooting
and diagnosing problems with your T102 and M501-TRS.
See Section 9.1.1.2 of this addendum
To check to see if your TRS  SO
1. Set the analyzer to TRS measurement mode (see the Setting the Gas
Measurement section in the T101 Manual - PN 07266).
2. Bypass the scrubber inside the M501-TRS.
a. Unscrew the pneumatic fittings from the scrubber.
b. Connect them with a stainless steel or Teflon
