Page Installation 8. Save the Certificate of Calibration shipped with this manual. Locate and save the Cleaner Kit included in the shipping carton. Page Water Fill 8. Filling the Saturator Note: Only distilled or deionized water should be used. The minerals in tap water may gradually contaminate the instrument and cause inaccurate readings. With power ON, remove the cap from the clear water reservoir. Using the supplied syringe, draw water into the syringe until full.
Basic Block Diagram Page Panel Description Air Inlet Sample In — Brings in room air for use in the system. An Instrument Air line may also be connected. Page 17 4. Keypad — A pressure-sensitive keypad that allows the user to program setpoints and to control functions.
Digital Output — RSC serial port for computer communication. Page Information Display Functions The Information Display It can be used as the primary interface with the instrument, showing status of all parameters, and allowing calibration points to be easily programmed.
Page 19 Note: The above three parameters may be programmed to be displayed in any desired sequence. A hum will be heard, indicating that the fans and vacuum pump are operating.
Page Programming The Rh-Cal Page 23 sample chamber can be set from 10 - 50 Deg. ABC Interval: Hrs. To do this, press ESC on the Keypad. Figure Locking In the Changes If you are not sure, or if you would like to make additional modifications to the program, press ESC on the Keypad and start over. Page Rs Serial Port Setup 4. If your sensor will be used to monitor a process for example that will always go from low RH to high RH, then calibrate it that way.
The hysteresis error will be eliminated. Allow sufficient time for chamber stabilization before calibrating sensors. In addition, allow sufficient time for the Sensor Under Test to completely equilibrate before calibrating each point.
Commands can be upper or lower case. The hold will be released when the ABC Cycle is complete and the instrument has stabilized back on the dew point. Page 29 NOTE: After an extended period of time in the cool mode, excess moisture or frost will form on the mirror. The time format is: Hours:Minutes:Seconds. Chilled Mirror Block Diagram The chilled mirror dew point sensor measures this parameter directly.
A highly reflective rhodium mirror is mounted to a solid state heat pump, or thermoelectric cooler. RH Calibrator. At least 90 days is typical. As contamination from the air sample gradually builds up on the mirror surface, an error in the indicated dew point reading could eventually occur. Page Maintenance Over time, particulates and other matter present in the sample gas that are not captured by filters build up on the mirror. Page Dryer Tube Maintenance distilled water, and wipe the mirror and surrounding areas again.
Dry these areas thoroughly with a clean, dry cotton swab. Replace the sensor cover and the sample chamber cover.
