Cmd parameter for the static pressure. After Reset
Adjustment, confirm the status by using Cal Status
of the cleared block.
The amount of adjustment made by the external
zero-adjustment screw can be reset to the initial
setting as well.
• Procedure to call up the calibration adjustment
parameter (Cal Cmd).
AI1, AI2 block : Cal Cmd : CAL_CLEAR
7.3.15 Software Write Protect
Hardware write protection and software write
protection functions are available for this
transmitter.
• Procedure to call up the protection setting
parameter (UAP Option)
UAPMO block : UAP Option

- Setting to enable or disable changing
the setting to the Diagnostic Switch and
Diagnostic Configuration parameters.
- Setting to enable or disable the hardware
write protection switch.
- Setting to enable or disable software write
protection.
• Procedure to call up the protection setting
display parameter (Hardware Write Protect)
UAPMO block : Hardware Write Protect
The Hardware Write Protect parameter enables
the switch status of hardware write protection to
be displayed.
For the relationship between hardware write
protection and software write protection, refer to
section 9. “Parameter Summary.”
7.3.16 Switching to Deep Sleep Mode
When the instrument will not be used for a long
time, switch the instrument to deep sleep mode to
conserve battery power. To switch to deep sleep
mode, follow the procedure below.
• Procedure to call up the switch-to-deep-sleep
parameter
TRANSDUCER block : Special Cmd
Set Deep Sleep mode(Standby) to the Special
Cmd parameter for the TRANSDUCER
block. To start from deep sleep mode, either
remove and insert the battery pack, or using
the provisioning device tool or the device
configuration tool via infrared communication.
CAUTION
After setting the deep sleep mode by infrared
device configuration tool, keep the infrared port
of device away from any other infrared signals.
NOTE
• Transmitter becomes the stop state after
setting deep sleep mode and cannot reply
any request from the device configuration
tool via wireless communication.
• For this reason, there is the case that an
error is display on the device configuration
tool via wireless communication.
• To wake up from deep sleep mode, please
pull battery pack and wait more than 30
seconds before attaching battery pack.
7.3.17 Switching to Silence Mode
This is a function to pause the instrument when
it cannot join the field wireless network after a
specified time has elapsed. This function is effective
in conserving battery power when, for example, the
installation of the field wireless integrated gateway
is delayed compared to that of field wireless
devices. The default value is 28800 seconds
(8 hours). Thereafter, a cycle of a one-hour
pause and six-minute search is repeated until the
instrument can join the field wireless network.
• Procedure to call up the switch-to-silence
parameter (Radio Silence)
UAPMO block : Radio Silence
Set 0 to 2
31 seconds for the Radio Silence
parameter of the UAPMO block. If 0 is set, the
Radio Silence parameter is invalid. To start from
deep sleep mode, either remove and insert the
battery pack, or use the provisioning device
tool or the device configuration tool via infrared
communication.
