IM 760401-01E
This function compares a preset limit and the measured, computed, or integrated value,
and outputs the determination result using relay contacts.
On models with the /DA4, /DA12, or /CMP option, the TTL logic signal (negative pulse)
can be used to control the WT210/WT230 or output externally.
External Input
The following five types of control signals are available.
EXT HOLD
Holds updating of the displayed values or releases the hold status.
EXT TRIG
Updates the displayed values in hold mode.
EXT START
Starts integration.
EXT STOP
Stops integration.
EXT RESET
Resets the integration result.
External Output
The following signal is output during integration.
INTEG BUSY
Outputs continuously from integration start through integration stop.
You can select GP-IB interface or serial (RS-232-C) interface. Measured/computed data
of up to 14 channels can be output to your PC via the communication interface. You can
also set various functions of the WT210/WT230 from your PC.
Measured/computed data can be printed on an external plotter or printer via the GP-IB or
serial (RS-232-C) interface.
Backup Function of Setup Parameters
This function backs up setup parameters (including computed values) if the power is
cut off such as a result of a power failure.
Initialization of Setup Parameters
This function initializes the setup parameters to factory default.
Zero Level Compensation
Zero level compensation refers to creating a zero input condition inside the WT210/
WT230 and setting the level at that point as the zero level. Zero level compensation
must be performed in order to satisfy the specifications of this instrument. When the
measurement range is changed, zero level compensation is performed automatically.
However, if the measurement range is not changed for a long time, the zero level may
shift due to environmental changes around the instrument. In such case, you can
manually perform zero level compensation.
Key Lock
Setup operations using front panel keys can be disabled except for the power switch
and KEY LOCK switch.
