22. Key Lock Function
The key switches of the balance and the IR sensor functions can be locked by sending a specified
command to the balance. This is a useful function when you want to control the balance only with an
external device such as a personal computer.
Even in the key lock state, it is possible to operate the keys with the key control commands. For the key
control commands, refer to
Key lock state can be checked by sending a command to check the state to the balance.
Key lock is maintained until either a command is sent to the balance to release or the power is turned
off by unplugging the AC adapter.
The key lock command operates only on the HOME screen (weighing mode, counting mode, percent
mode, minimum weight alert function). Although the key lock command operates in compounding mode
and HPLC mode, you cannot operate the balance with the command (the SAVE button
selection).
Caution The IR sensor settings cannot be changed in the key lock state.
