DISPLAY/OPERATION
Parameters are set by an hot-plugged display TXDIN70-Display. Apart from nitial set-up, TXDIN70Display can be stay connected serving as an external display.
1 Upper Display: Displays PV of channel 1 or parameter
code, When the display keeps flashing or the reading is
abnormal, please check the input specification whether it is
correctly set.
2 Lower Display : Displays PV of channel 2 or parameter
value. When the display keeps flashing or the reading is
abnormal, please check the input specification whether it is
correctly set.
3 Set Key: Accessing parameter table and to confirm
parameter change.

Remark: The bundled IEEE-1394 cable is designed for
communication between TXDIN70-Display and TXDIN70. This
cable is not for other usages.

FIL=0, no filtering;
FIL=1, filtering with mean;

When a large value is set, the measurement input is
stabilized but the response speed is slow. Generally, it can
be set to 1 to 3.
If great interference exists, then you can increase parameter
FIL gradually to make momentary fluctuation of measured
value less than 2 to 5.
When the instrument is being metrological verified, FIL can
be set to 0 or 1 to shorten the response time.
OPn=1, For 1 input 1 output or 2 inputs 2 outputs

OPn=2, For 1 input 2 outputs retransmission (Outputs from
input channel 2).
