Autozero
This equipment features an autozero function.
This allows the zero point to be restored without affecting the span point if disturbed by sample removal
or attachment, for example.
Pressing the
key enables the autozero function and forcibly resets the torque value to [0]. However,
the autozero function cannot be enabled if correction totaling ±10 % has been performed using the zero
function.
(
flashes on the torque display.) It can also be enabled using the "A/Z" external control
input signal.
Key Lock
Key lock is a function that restricts operations to prevent accidental operation of the various keys on the
front panel.
Setting each digit for function mode F-18 to 0 disables the corresponding key lock, and setting to 1
enables the corresponding key lock.
By default, key lock is disabled for all keys. For details of the operating procedure, see "9. Function
Mode".
Note that keys affected by key lock correspond to the setting digits as follows:
Setting range: 00000 to 11111
0: Key lock off
1: Key lock on

Note that if the
key is locked, pressing the
key for at least 3 seconds while depressing the
key unlocks the
for one time.
Those keys that are locked will not function even when pressed.
