ValveSight Diagnostics for HART User Manual FCD VSENSF0001-02-AQ 03/15

At the bottom of each screen in the Analog Output Calibration is a Status ﬁeld that indicates any actions required or if the

process is ready for the next step.

The ﬁrst screen of the Analog Output Calibration Wizard requires no input. Click the

button to start the wizard.

Instructions are provided on the screens that follow.

8.4 Analog Input

The Analog Input Calibration provides a way to change the relationship between the 4-20 mA input and the stroke of the

valve. This calibration is required if the 4-20 mA signal to the positioner needs to be spanned to something other than

4-20 mA. The calibration values are updated to match the stroke calibration of the positioner automatically every time a

stroke calibration is done.

The Analog Input calibration must have an external current source connected to complete the calibration.

Monitor

The “Monitor” box shows the Command A/D input value. This reﬂects the value of the command signal before it is con-

verted to %. The Design Current shows the current detected by the positioner.

Calibration Flags

The “Calibration Flags” display box indicates alarms that can become active if errors occur during calibration. The 0%

Signal Out of Range error indicates that the current supplied for the 0% position is not correct. The 100% Signal Out of

Range error indicates that the current supplied for the 100% position is not correct. The Range Too Small error indicates

that a larger current span from 0% to 100% is required.

At the bottom of each screen in the Analog Input calibration is a Status ﬁeld that indicates any actions required or if the

process is ready for the next step.

The ﬁrst screen of the Analog Input Calibration Wizard requires no input. Click the

button to start the wizard. In-

structions are provided on the screens that follow.

9 Conﬁguration

The purpose of the Conﬁguration screen is to redirect the user to the various Conﬁguration screens or to any of the main

navigation screens.
