IM 01C27H01-01EN
■ Using the Device Configuration Tool
Refer to subsection 7.3.14 “Zero-point
Adjustment and Span Adjustment”.
(2) When you cannot obtain the Low Range
Value from the actual measured value of
0%;
Adjust the transmitter output to the actual measured
value obtained by a glass gauge, etc.
[Example]
The measuring range of 0 to 2m; the actual
measured value of 0.8m
0.8
2
Actual measured value= x100=40.0%
■ Using the transmitter’s zero-adjustment
screw
Turn the zero adjustment screw to match the
output signal to the actual measured value.
■ Using the Device Configuration Tool
Refer to subsection 7.3.14 ”Zero Point
Adjustment and Span Adjustment”.
6.3 Starting Operation
After completing the Zero Point Adjustment,
follow the procedure below to start operation.
1) Confirm the operating status.
2) After confirming the operating status, perform
the following:
IMPORTANT
• Close the terminal box cover and the
amplifier cover. Screw each cover in tightly
until it will not turn further.
• Tighten the zero-adjustment cover mounting
screw to secure the cover.
6.4 Connecting to the Field
Wireless Network
■ Preparation work prior to connecting to a
Field Wireless Network
This transmitter does not need to be connected
with a physical wire. Instead of physical wiring, it
is necessary to set the field wireless devices to
communicate with before installing the transmitter.
This procedure is called a provisioning.
This transmitter supports provisioning via infrared
communication using a provisioning device and
can be securely connected to a network. If the
provisioning information is not set, the transmitter
cannot be connected to the field wireless network.
Provisioning:
Provisioning is work to set the security and
network information to enable the transmitter
to be connected to the field wireless network.
This transmitter supports a provisioning method
using infrared communication.
For details on provisioning using a provisioning
device, and procedure for connecting the
transmitter to the Field Wireless Network, refer
to the User’s Manual, FieldMate Versatile Device
Management Wizard (IM 01R01A01-01E),
YFGW710 Field Wireless Integrated Gateway (IM
01W01F01-01EN) and YFGW410 Field Wireless
Management Station (IM 01W02D01-01EN).
