Calibrate; Factory - MTS Systems Level Plus Interface Manual

float (Prod Trig Lvl) and the Interface float (Int Trig Lvl). If the Interface
float is not active no signal can be viewed.

9.3.2 Calibrate

Product Level
Allows the user to change the level in engineering units if needed.
Typically this is not needed for analog output units. The user should
use the Current Level selection and enter the current position of the
float. The user is advised not to use the Offset feature without help from
Technical Support.
Interface Level
Allows the user to change the level in engineering units if needed.
Typically this is not needed for analog output units. The user should
use the Current Level selection and enter the current position of the
float. The user is advised not to use the Offset feature without help from
Technical Support.

9.3.3 Factory

Settings
Menu section that contains factory parameters. Do not edit these para-
meters without talking to Technical Support.
Gradient
The gradient is a calibration factor that is unique for each transmitter.
Typical values are between 8.9 and 9.2 µs/in.
Serial Number
The Serial Number is the unique identifier for the unit from MTS and
should not be changed. The serial number is used for tracking and
determining spare parts.
SARA Blanking
Initial blanking distance from the head of the level transmitter. Do not
change.
Magnet Blanking
Blanking distance between two floats. Do not change.
Gain
Measurement of how large an interrogation signal is used. Do not
change without Technical Support.
Min Trig Level
Threshold level for return signal to qualify as a valid signal and not noise.
Temp Setup
Allows the user to turn the temperature measurement on or off. Turning
it on will not cause the temperature to work if no temperature measure-
ment was ordered.
No. of Temp
Change the number of temperature points the level transmitters is
looking for. Changing this number does not change the number of
temperature measurement points that were ordered or whether or not
temperature measurement was ordered.
Float Config
Allows the user to enable or disable the product float (Loop 1) and/or the
interface float (Loop 2). The first float measured by the electronics will
be used as the product float. If the interface float is turned on and there
is no second float both loops will go into alarm.
Damping
Damping slows the rate of change for the output signal. It does not
change the output but dampens how quickly the output follow the change
in the float position. The standard rate of change would have the Dam-
ping set to 3276. Loop 1 and Loop 2 can be dampened independently
Auto Threshold
Do not disable.
Reset to Factory
Allows the user to reset the electronics to the original factory settings.
This should be used to return the electronics to a known good state when
troubleshooting.
