METTLER TOLEDO AT/MT/UMT Balances

Command Acknowledge

Function: Turns the command acknowledge mode on or off.

Description:

is either 0 or 1.

EC 1 turns command acknowledge on. This causes the balance to

send the message OK after every command that it has recognized

as correct. This signifies that it is ready for a new command.

EC 0 or EC without parameter switches back to normal mode (no

acknowledge).

EC ? reports the current mode as follows:

EC=0 command acknowledge off

EC=1 command acknowledge on

An OK message does not necessarily mean that the command has

been fully executed. With the tare command, for instance, OK

appears as soon as taring begins. With an unstable weighing signal,

however, it can take several seconds until the display has achieved

stability and taring can be completed.

Error messages (EL, ES or ET) override the OK message.

Error: EL if the handshake mode is set to METTLER TOLEDO CL. In this

mode the character ACK assumes the role of the OK message.

Format: EC[
