46
Parameter 76 Debug mode for Event monitors and Scale Basic
The Debug mode is used to ‘debug’ event monitors and scale basic functions. Enter a 1
to activate debug mode, enter a 0 to disable debug mode. When debug mode is enabled
Scale Basic functions ‘single step’. The subroutine stack level and the Function number
are displayed when entering a function. Example: “0 F12”. Press the ENTER key to
begin execution of the function. The instruction address and instruction code are
displayed. Example: “21 255”. Continue to press the ENTER key to step thru the
program. NOTE: the first step displayed for all scale basic functions is a GOTO (244).
Function 78 Initialize ID memory
Use function 78 to initialize id memory after it has been corrupted. The ID memory
becomes corrupted when power is lost (when battery backup is disabled) or when the
battery is allowed to discharge below 2 volts.
Parameter 79 Enable Multi-point Linearization
Enter a to 1 to enable multi-point Linearization, enter a to 0 to disable multi-point
Linearization. The IDS 440 uses the calibration factors set in function 80 below when
multi-point Linearization is enabled.
Function 80 Calibrate - Multi-point Linearization
Use function 80 to calibrate the scale using up to 5 calibration points to 'linearize' the
load cell. Set the Scale Operation Parameters before using function 80. Best results are
obtained when the IDS 440 and load cells have reached thermal equilibrium (power
applied for approximately 30 to 120 minutes depending on load cell size). NOTE:
function 80 automatically adjusts parameter 19 (deadload offset).
1. Hold the CLEAR key down and press the ENTER key to enter the configure mode.
2. Enter CFG 80. The IDS 440 prompts "dEAdld". Remove all weight from the scale.
Press the ENTER key to obtain the deadload weight. Press the Units key ( ↓) to
continue without reading a new deadload weight.
3. The IDS 440 ‘s display alternates between "CAL 1" and the weight on the scale.
Place the first calibration weight on the scale. Enter the calibration weight using the
numeric keypad. Press the ENTER key. The IDS 440 reads the calibration weight.
4. The IDS 440 ‘s display alternates between "CAL 2" and the weight on the scale.
Repeat step 3. The IDS 440 will accept up to 5 calibration points. Press the CLEAR
key to complete calibration if less than 5 calibration points are used.
5. The IDS 440 prompts "CFG 80". Press the CLEAR key to exit the configure mode
