Operation
When power is applied to the system it initially displays the model type 3 seconds
while the processor initialises the four channel calibration constants to their last
known values. On completion, the system enters the normal mode and continuously
displays the four current transducer values.
The 9 available functions are accessed by pressing the function key indicated by a
circular arrow on the keypad. Each press of the key steps to the next function until
finally it returns to the normal display mode. Alternatively, with the exception of the
“Calibration Functions” the system will automatically time out after approximately 10
seconds and return to the normal mode. The function are accessed in the following
order
The Function Key
Level 0 = Normal display mode
Level 1 = Select Channel
Level 2 = Tare selected channel
Level 3 = Calibrate selected channel
Level 4 = Set decimal point position
Level 5 = Display model and serial number
Level 1 = Select Channel
This selects the channel number that the tare and calibrate operations will use. This
is indicated on the display with 3 arrow adjacent to the reading i.e. “<<<”
Level 2 = Tare channel
The display gives two options, either press ENT key
to tare this input or
press the CLR
key to remove any tare value.
