5 Calibration and Sealing
To calibrate a scale the indicator must be placed in calibration mode. Only
qualified scale technicians should be performing these operations. The 3 scale
channels are independent of each other and must be calibrated separately.
5.1 Placing the indicator into Calibration Mode
To calibrate channel 1 press 19 followed by the print select key.
To calibrate channel 2 press 29 followed by the print select key.
To calibrate channel 3 press 39 followed by the print select key.
Note that standard OnBoard and Mobile Multiple Animal applications use
single channel indicators. Channels 2 and 3 are not available.
The display will be showing a blinking “PASS” message. This prompts you
to enter a 4 digit password. Key presses are not displayed on the display. If
the 4 digit password sequence is correct then the indicator will automatically
enter calibration mode.
The factory default for the password is 1111. This can be changed but we
recommend keeping the password to the factory default, more on this later.
You have 30 seconds to enter calibration mode before the indicator cancels
and returns back to normal weighing mode.
Calibration mode is indicated when there is a blinking ‘C’ displayed in the
left most digit on the display.
5.1.1 Special Keypad function keys during calibration
5.1.1.1 Selecting a calibration parameter.
The M2000 uses parameter numbers to access calibration functions. Each cal
function has a unique number used to access that parameter. In calibration
mode the print select key now becomes the calibration function select key.
Entering a calibration function number followed by the print select key
selects a calibration parameter to edit. Immediately after a function
parameter has been entered followed by the print select key the value of that
parameter will be displayed on the display for a short period of time.
5.1.1.2 Editing a calibration parameter.
After selecting a cal parameter with the print select key a new value for that
cal function can be entered. The TARE key now becomes an ENTER key for
entering calibration parameters. Parameter values entered from the keypad
must immediately follow with the TARE key to take affect.
