• Procedure to call up the calibration
adjustment parameter (Cal Cmd).
AI1 block: Cal Cmd: CAL_HIGH
Set the upper limit of the measurement range
in CAL_HIGH of the differential pressure (AI1
block) Cal Cmd parameter.
• Procedure to call up the calibration status
parameter (Cal Status).
AI1 block: Cal Status
Confirm the value of CAL_SUCCESS (1)
using the Cal Status parameter.
(3) Adjustments for Static Pressure
For the EJX differential transmitters, zero point
and span adjustments of static pressure is
performed in the same way as with the primary
process variable (PV).
Adjustment should be performed using the
static pressure (AI2 block) Cal Cmd parameter.
After calibration, confirm the status by using the
static pressure (AI2 block) Cal Status.
• Procedure to call up the calibration
adjustment parameter (Cal Cmd).
AI2 block : Cal Cmd
Perform differential pressure zero/span
adjustment before static pressure zero/span
adjustment.
(4) Reset Adjustment
Reset Adjustment clear the amount of
adjustment. Reset Ajustment can be performed
using CAL_CLEAR of the differential pressure
(AI1 block) Cal Cmd parameter for the input
pressure and using CAL_CLEAR of the static
pressure (AI2 block) Cal 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
8.3.12 Software Write Protection
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
The following settings can be configured in the
UAP Option parameter.
- 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 10. “Parameter Summary”.
8.3.13 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 use
the provisioning device tool or the device
configuration tool via infrared communication.
