Page 16: Warranty And Claims
Process photometric analyzers, process moisture analyzers, and sample systems are warranted to perform the in- tended measurement, only in the event that the customer has supplied, and AMETEK has accepted, valid sample stream composition data, process conditions, and electrical area classification prior to order acknowledgment. The photometric light sources are warranted for ninety (90) days from date of shipment.
Page 17: Chapter 1 Overview
OVERVIEW The AMETEK Model 931S and Model 932S UV Analyzers use photometric analysis to continuously monitor H S levels in acid gas (and other) ap- plications or other high dewpoint applications. The microprocessor-based Model 931S and Model 932S Analyzers minimize the complexity of these tasks and simplify operation of the analyzer system.
Page 18: About The Analyzer

Page 66: Hardware Configuration (Modbus Tcp Communication)
Hardware Configuration (Modbus TCP Communication) If using Modbus TCP to communicate with the analyzer (via the AMETEK S93XS System 200 Configurator Software), a TCP module must be in- stalled and set up before communication between the computer and ana- lyzer can be established. This type of communication connection can be used for configuring and servicing the analyzer, without the use of a serial cable.

Page 91: Adjusting Analyzer Controls For Normal Operation
Adjusting Analyzer Controls for Normal Operation Setting the Sample Gas Flow Rate and Sample Response Time Sample response time is determined by switching the analyzer’s Flow Control mode from ‘2’ (zero) to ‘0’ (auto) and recording the time it takes the analyzer to display the first reading after the switch.
Page 92: Setting The Zero Gas Flow Rate
This is less critical if plant nitrogen or instrument air is being used as the Zero gas.  Set the response time first to ensure a good zero. NOTE Some applications may require a higher flow rate. 3-46 | Model 931S / Model 932S UV Analyzers...
Page 93: Normal Operation
Recording Initial Readings AMETEK recommends that you observe and record this information monthly to obtain a history. From these recordings, you will be able to determine if there are problems with the analyzer, such as diminishing PMT signals, or increasing sample response time.
Page 94: Recording Initial Sample Response Time
Flow Control mode from ‘2’ to ‘0’ is approximately 15 seconds), no further adjustment is necessary. The sample response time may vary, depending on Sample Line  length. NOTE 4. Record these signals in a log book every month. 3-48 | Model 931S / Model 932S UV Analyzers...

Page 254: Recommended Preventive Maintenance Spare Parts
Because the Model 931S and Model 932S Analyzers are designed to ac- commodate a wide variety of applications (and therefore can accommo- date a variety of sample system components), there is no typical spare parts list available for the analyzer’s Optical Bench and sample system.
Page 255: Spare Analyzer Fuses
Spare Analyzer Fuses AMETEK recommends having on-site spare fuses used in the analyzer. These fuses do not need to be changed out at regular intervals, but are necessary in the event that a fuse has blown and a replacement is required.
