This sub-menu enters the values that will be used by the instrument when it cali-

CALIBRATION TYPE
The transducer output when its full-scale displacement is applied to it, in Volts
RMS (root-mean-squared) assuming 3 VRMS excitation. 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 issued by its manufacturer.
This enters the engineering units for the known-displacement calibration points.
These points must match the actually displacements that you will apply to the
transducer during calibration. The number of calibrations points depends on the
.
CALIBRATION TYPE
When using the 2-Point Known Displacement Calibration type, the following menu
items are available:
• " ": point 1 of 2, usually 0% of the transducer's full-scale capac-
KNOWN POINT 1/2
ity.
• " ": point 2 of 2, usually 100% of the transducer's full-scale
KNOWN POINT 2/2
capacity.
When using the 3-Point Known Displacement Calibration type, the following menu
items are available:
• " ": point 1 of 3, usually 0% of the transducer's full-scale capac-
KNOWN POINT 1/3
ity.
• " ": point 2 of 3, usually 50% of the transducer's full-scale capac-
KNOWN POINT 2/3
ity.
• " ": point 3 of 3, usually 100% of the transducer's full-scale
KNOWN POINT 3/3
capacity.
When using the 5-Point Known Displacement Calibration type, the following menu
items are available:
• " ": point 1 of 5, usually 0% of the transducer's full-scale capac-
KNOWN POINT 1/5
ity.
• " ": point 2 of 5, usually 25% of the transducer's full-scale capac-
KNOWN POINT 2/5
ity.
• " ": point 3 of 5, usually 50% of the transducer's full-scale capac-
KNOWN POINT 3/5
ity.
• " ": point 4 of 5, usually 75% of the transducer's full-scale capac-
KNOWN POINT 4/5
ity.
• " ": point 5 of 5, usually 100% of the transducer's full-scale
KNOWN POINT 5/5
capacity.
NOTICE
To insure both correct operation of the transducer and application of the dis-
placement, the instrument expects the voltage applied at each known-displace-
ment point to be increasing. For example, the displacement applied at Known-
Displacement Point 2/2 must cause the transducer to produce a more positive
voltage than at Known-Displacement Point 1/2. You may need to swap the
(+)Signal and (-)Signal wires on the 12-pin channel connector to accomplish
this.
