3.2 Special Keypad Functions
Keypad functions are selected by entering a numeric function code on the
keypad followed by the PRINT SELECT key. Some functions are marked on
the key itself. The most common functions are discussed below.
3.2.1 Selecting scale channels
The M2000 has three independent scale channels. Press the channel number
followed by the PRINT SELECT key as shown below.
To select channel 1 press 1 followed by the print select key.
To select channel 2 press 2 followed by the print select key.
To select channel 3 press 3 followed by the print select key.
Note: that by default only channel 1 is enabled. To enable channels 2 and 3
you must enter calibration mode and use parameter 98 to enable them.
Trying to select a scale channel that is not enabled will display error
message 40.
3.2.2 Summing channels in TOTAL mode
Up to 3 channels may me summed together to display a total weight. An
example of an application that may require this operation would be a truck
scale with three sections. Each section would be a separate channel on the
indicator allowing the operator to simultaneously record the total weight of
the vehicle along with the individual axle weights of the truck.
To enter total mode press 4 followed by the print select key. Total mode
must be enabled before it can be used. Parameter 70 in calibration mode is
used to enable the total mode function. Enter 1 followed by the TARE key to
enable TOTAL mode. Total mode
cannot be used for legal for trade
applications in Canada. Only channels that are enabled and calibrated with
the same grad size, decimals and units of weight will be displayed in total
mode. Total mode is indicated by illuminating more than one channel on the
channel indicators. Channel 1 is always part of the total.
Example:
Ch1 and 3 are calibrated as 2000 x 2 lbs and Ch2 is calibrated to 500 x 0.2 lb
. When you press 4 followed by the PRINT SELECT key the CH1 and CH3
indicators will illuminate showing that the weight on the display is the sum
of these two channels. Channel 2 however is excluded from the total as it is
calibrated in 0.2d instead of 2d for channels 1 and 3.
When the indicator is in TOTAL mode all the channel operations are
combined. Pressing the ZERO button will zero all the channels that are part
of the total. The TARE function will tare all channels simultaneously
