5.2 Display Units The 1735 can calculate the water vapour content in several different units. The format of the oxygen display changes to maintain the best resolution for the measurement. Units Display format Water vapour (WV) ##.# % Dew point (DP) ##.# °C (°F) Probe oxygen (O 2 ) See the table below Absolute humidity (AH) # g/Kg or #.# Kg/Kg Mass fraction (MF) # g/Kg If oxygen is selected for the top line the transmitter will show the oxygen in % format between 100% down to 0.1%. Below of this range the oxygen will be shown in scientific format. Range Display format 30.0% to 100.0% ###.# % 1.00% to 29.99% ##.## % 0.100% to 0.999% 0.### % < 0.100ppm scientific notation (#.## x 10 - ## % ) April 2012 34 1735 Water Vapour Transmitter
5.3 Keypad There are eight keys built into the decal on the outside of the door of the 1735 transmitter. The key functions are written in BLACK and WHITE to identify the function of the key in either RUN mode or SETUP mode. Key text RUN mode (WHITE text) SETUP mode (BLACK text) SETUP / RUN Enter SETUP mode Return to RUN mode DISPLAY / FUNCTION UP Display Next Lower Line Item Next Function DISPLAY / FUNCTION DOWN Display Prev.

The key functions in this mode are as follows; SETUP / RUN key Pressing this key will put the transmitter into one of the menu-driven SETUP, COMMISSIONING or CALIBRATION modes (see chapters 6, 7 and 8 for details). The function of all the keys will then change to the functions that they have in the SETUP mode. DISPLAY UP / DOWN keys The display keys are used to scroll the lower line up and down through the variety of measurements that are available on the lower line. For a complete list of options see chapter 6.3.2, Lower Line Items. ALARM UP key If there is either a new alarm or an active alarm the ALARM UP key can be pressed to examine the alarm status. The alarm light will be flashing if there is a new alarm or steady if there is an existing alarm. For more details on the alarm mode and keys see chapter 9, Alarms. The SETUP light will flash slowly to show that the transmitter is now in the alarm display mode. ALARM DOWN key When the transmitter is displaying active alarms (the ALARM UP key has been pressed), the ALARM DOWN key and the ALARM UP key allow the operator to examine the date / time of the alarm and the date / time that the alarm was acknowledged. If the transmitter was in RUN mode when this key is pressed it will go into the alarm log display mode. See chapter 9 for more details. ALARM ACCEPT key The ALARM ACCEPT key is used to accept a new alarm (see chapter 9, Alarms). GAS 1 / PURGE 1 and GAS 2 / PURGE 2 keys These two keys are used to turn on the gas / purge solenoids. When the transmitter is in the manual cal / purge mode (Commissioning functions #21 and 30) the solenoid will be activated for as long as the key is pressed. When the transmitter is in the auto cal / purge mode the automatic cal / purge cycle is started. The cycle can be stopped by pressing the same key again. April 2012 1735 Water Vapour Transmitter 35
