In this mode the top line of the display will show the selected units of humidity from probe 1. The other key functions are – SETUP / RUN Key Pressing this key once will put the transmitter into the SETUP mode. The function of all the keys will then change to the functions that they have in the SETUP mode. Pressing the SETUP / RUN key again will return the transmitter to the RUN mode, or it will return automatically one minute after the last key press. DISPLAY Up / Down Keys The display keys are used to scroll the lower line up and down through the variety of measurements that are selected on the lower line display. The list can be changed to suit the operator by using SETUP function #3. 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. (see chapter 6, Alarms). ALARM Down Key When the transmitter is in the run mode or the alarm mode (the ALARM UP key has been pressed), the ALARM DOWN key and the ALARM UP key allow the operator to examine the alarm log. The date / time of last 4000 alarms can be scrolled through. Each alarm record consists of the alarm name and the date / time that the alarm was initiated, accepted and cleared (see chapter 6, Alarms). ALARM Accept Key The ALARM ACCEPT key is used to accept a new alarm (see chapter 6, 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 function #22/31) 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.
