6-1-1. Equivalent circuit of external input
6-1-2. Explanation of the function
(1)
A/Z ON
When the “A/Z ON” switch at the front panel is pressed, or shorten the terminal between A/Z
ON and COM for about 100 ms or more, auto zero (tare weight cancellation) is executed, and
teh voltage output value and the current output value becomes zero. The voltage output value
or the current output value becomes the output for net weight.
(2)
A/Z OFF
When pressing the “A/Z OFF” switch, or shorten the terminal between A/Z OFF and COM for
about 100 ms or more, the function of auto zero clear (tare weight cancellation clear) will work.
The voltage output value or the current output value becomes the output of gross weight.
Caution
●
Dont press the A/Z ON switch in the condition of pressing the A/Z OFF switch. It enters the adjustment mode for our maintenance, and it
becomes a fixed output of DC0 V compulsorily, and AUTO ZERO LED blinks.
Please push the A/Z ON switch with the A/Z OFF switch pushed again, and make clear the adjustment mode when it enters the adjustment
mode by mistake.
●
The operation of A/Z ON and A/Z OFF by the external control input is started when the input signal is shorten for about 100 ms or more.
●
Don
’
t execute the A/Z OFF during the 1 second executing the A/Z ON by the external control input and the switch at the front panel.
●
When the optional auto zero is attached, the temperature effect of auto zero is added on the standard temperature effect.
●
When the condition changes by the external control input, please confirm the timing of the changeover, and adjust the timing by processing
the timer if necessary.
