The LCD will now display the current High or Low range value. Use the '5', ' 6', ' ', &
'↵' keys to enter the new value. Pressing the ' ↵' key confirms and saves the new range
setting and returns to the 'Lo' or 'Hi' display. The other range limit can now be set by
following the same process if required. Pressing the '5' key returns to the ' VoLt' display.
Note – Once the enter key is pressed to set either the high or low range limit, that value is written to
memory and will not revert to the previous value even if the 60 second timeout occurs.
9.7 ACAL
Description – The ACAL menu option allows the user to Auto Calibrate any DT45
transmitter using the DS5000. Although the process is controlled and driven from the
DS5000, the Auto Cal values are stored and implemented in the transmitters, thus allowing
complete interchange ability of transmitters. Before starting this procedure, ensure that the
DT45 has been exposed to a known steady state moisture level for at least 10 minutes.
Operation – While 'ACAL' is displayed press the ' ↵' key to enter the subroutine. If the
DS5000 is set-up to require a security code, the LCD now displays 'codE' for 2 seconds
followed by '0000'. Use the ' 5', ' 6', ' ', & ' ↵' keys to enter the current ACAL security
code. If no code is required or the correct code is entered the LCD changes to 'rEF' followed
2 seconds later by '0000'. Use the ' 5', ' 6', ' ', & ' ↵' keys to enter the moisture level at
which the Auto Calibration is being performed. When the '↵' key is pressed, the DS5000
performs the Auto Calibration process on the DT45, which takes approximately 5 seconds
during which time 'CAL' flash's on the LCD. The word 'SEt' is then displayed on the LCD
until the '↵' key is pressed. The ' ↵' ke y implements the Auto Calibration results and exits the
System Menu.
9.8 oFSt
Description – The oFSt menu option allows the user to superimpose an offset upon any DT45
transmitter using the DS5000. Although the process is controlled and driven from the
DS5000, the offset values are stored and implemented in the transmitters, thus allowing
complete interchange ability of transmitters.
