The K3TS retains the value calibrated to zero even if the K3TS is turned off.
To cancel zero-shift state, change the prescaling value (if the prescaling val-
ue should not be changed, go to the prescaling menu to reconfirm the X

values, and the position of the decimal point using the Display Key and
then return to the RUN mode) or the input range. Check that the ZERO indi-
cator is OFF when zero-shift state is canceled.
To input a ZERO input signal from a transistor such as a sensor, use an open
collector configuration with a transistor that has a minimum collector current
of 5 mA or less.
The zero-shift value of the K3TS with forced zero RAM specifications will be
lost when the K3TS is turned off.
Each time forced zero is turned ON on the standard K3TS, the shifted value
will be written to the internal non-volatile memory (EEPROM). The data will
not be lost even if the K3TS has a power failure. The EEPROM can be over-
written approximately 100,000 times. For applications in which the forced
zero function is used more frequently, please use the K3TS-SD21B-
with
forced zero RAM.
When the process value is shifted to zero on the K3TS with a display shift
function, the calibrated value will be set in the display shift menu as the shift
value. For example, if a process value of 100 is shifted to zero,
will be
displayed as the shift value.
To cancel zero-shift state, change the input range or set the display shift val-
ue to
, at which time make sure that the ZERO indicator is lit.
Each time forced zero is turned ON on
the standard K3TS, the shifted value
will be written to the internal non-volatile
memory (EEPROM). The data will not
be lost even if the K3TS has a power
failure. The EEPROM can be overwrit-
ten approximately 100,000 times. For
applications in which the forced zero
function is used more frequently, please
use the K3TS-SD21B-
with forced
zero RAM.
