(16) Test Output Setup
(K10: OUTPUT X %)
This feature can be used to output a fixed current
for loop checks. The available range for test output
depends on the setting at parameters D20: OUT
LIMIT (L) and D21: OUT LIMIT (H), whose limit is
from 3.6 mA (–2.5%) to 21.6 mA (110%).
• Example: Output 12 mA (50%) fixed current.

NOTE
• Fixed current output and DO Test continue
for a given holding time, then is released
automatically. Even if the BT200 power
supply is turned off or the communication
cable is disconnected, the test output will
continue for that time.
The holding time can be selected from 10
min*, 30 min, 60 min, 3 hour, 6 hour or 12
hour by the parameter K45: TEST TIME.
*: Default value.
• Press the
(OK) key to release test output
immediately.
(17) Signal Characterizer
This function is used to compensate the output
for non-linear applications. The characterized
values are applied to the 4-20 mA output. For
the measured pressure, a maximum of nine
coordinates can be specified between 0-100%.
Perform the coordinate settings while the T10: S. C.
ENABLE parameter is
INHIBIT
.
To apply the settings to the output, set the T10: S.
C. ENABLE parameter to
ENABLE
.
Note that the transmitter rejects the activation of the
function by AL. 60 with the following transmitter’s
status:
• When the specified coordinates of x and y are
not incremental as the input increases.
• When the output mode of the output signal is
set as
SQUARE
ROOT
; at the same time, the
low cut mode is set to
LINEAR
.
