8 Programming the DS5000
8.1 Principle of Entering Numerical Data
Wherever a numerical number has to be entered into the DS5000 the following text will be
found. "Use the '5', '6', ' ', & '↵' keys to enter ......". The basic principle used to
enter numerical values (integer and floating point) is described here.
The first character of the LCD display flashes to indicate it is active. Use the '5' and '6'
keys to select the required number between 0 and 9 (-1 and 9 in some engineering units) then
press the ' ' key to make the second character flash. Use the '5' and '6' keys to select
the required number between 0 and 9 then press the ' ' key to make the third character
flash. Continue this process until all four characters are entered. In the case of a floating-point
numbers, press the ' ' key again makes the decimal point (dp) active. Use the '5' and
'6' keys to position the dp in the required position. A subsequent press of the ' ' key
makes the first character active again. Pressing the '↵' key at any point confirms the
numerical value.
Note – The Passwords used within the DS5000 are made off four integers and does not use the dp.
Note – The only way to leave the numerical part of this routine without saving it is to allow the 60-
second timeout to occur.
9 Configuring the DS5000
To activate the Systems Menu press the key sequence '↵' ' ' '↵'. This will display the
'SYS' message on the LCD as portrayed in the System Menu Map (see Appendix A).
Pressing the '↵' key again enters the system menu map at the 'unit' screen on the base level.
There are 11 base level options described below:
Note: The default set-up will go directly from the SYS message to the unit screen. However, if the user
has set a SYS password, then the user is prompted to enter the correct password before continuing on to
the base level.
Note: Most of the screens within the menu have an active 60-second timeout. Therefore, if no keys are
pressed within this period the unit reverts automatically to normal operation. In most cases where the
60-second timeout occurs, changes made are not implemented.
9.1 unit
Description - The unit menu option allows the user to select the required engineering units
(See DS5000 Specification section 14 for details). Once the engineering unit is selected the
DS5000 will only display and accept inputs in that chosen unit.
The current engineering unit is displayed in the seven segments LED during normal operation
Note: When the engineering unit is altered, the LCD display changes to show the current moisture level in the
selected unit.
