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

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 Conguration Tool

Refer to subsection 7.3.14 ”Zero Point

Adjustment and Span Adjustment”.

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 eld 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 eld wireless network.

Provisioning:

Provisioning is work to set the security and

network information to enable the transmitter

to be connected to the eld 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).
