to the transducer. The menu items that are displayed will change according to
what the is set for.
CALIBRATION TYPE
The nominal transducer/amplifier output when its full-scale load is applied to it, in
volts or milliamps. This menu item is used by the instrument to set gain of its
amplifier circuit. This value is normally found on the transducer's Certificate of
Calibration or amplifier's Application Note.
The transducer's full-scale output in engineering units.
It is available only with the Shunt Calibration type.
The transducer's zero-scale output in engineering units, which is usually zero.
It is available only with the Shunt Calibration type.
The shunt calibration value must be calculated by using information found on the
transducer's Certificate of Calibration and the following formula:
=
SHUNT CAL VALUE
The terms have the following meanings:
• Shunt-Calibration Output: The transducer's output when its shunt calibration
function is activated in Volts or milliamps. Sometimes called "Shunt Cal. Fac-
tor".
• Full-Scale Output: The transducer's full-scale output in Volts or milliamps.
Sometimes called "Calibration Factor".
• Full-Scale Capacity: The transducer's desired full-scale reading in engineering
units (PSI, lbs, Kg, etc.). You may wish to convert the engineering units of this
value. For example, if the transducer full scale is 3000 PSIG and you wish the
channel to read in bar, you must convert 3000 PSIG into 206.84 bar.
This menu item is only available with the Shunt Calibration type.
To verify proper transducer/amplifier operation, you can activate the transducer's/
amplifier's shunt calibration function while the instrument is in the RUN mode.
Press and hold the [ENTER] button for three seconds; this will activate the trans-
ducer's/amplifier's shunt calibration function and display the reading.
This enters the engineering units for the known-load calibration points. These
points must match the actual loads that you will apply to the instrument during cal-
ibration. The number of calibrations points depends on the
