“
SHUNT CAL VALUE
” register.
• “
TYPE= MV/V CAL
” means Millivolt-per-Volt Calibration. First, you are prompted to
apply the load entered in the “
ZERO SCALE VALUE
” register. Next, the instrument
takes a reading from an accurate, internal mV/V reference. The instrument
then uses the “
FULL SCALE MV/V
” and “
FULL SCALE VALUE
” values in mathematical
calculations to scale its tracking values.
• “
TYPE= 2 POINT CAL
” means 2-Point Known Load Calibration. You are prompted
to apply the loads to the transducer that were entered in the “
KNOWN POINT 1/2
”
and “
KNOWN POINT 2/2
” registers. This technique assumes that the transducer is
linear, so the usual loads used are zero scale and full scale.
• “
TYPE= 3 POINT CAL
” means 3-Point Known Load Calibration. You are prompted
to apply the loads to the transducer that were entered in the “
KNOWN POINT 1/3
”
and “
KNOWN POINT 2/3
” and “
KNOWN POINT 3/3
” registers. This technique can be
used to compensate for the non-linearity in the transducer. The usual loads
used are zero scale, half scale and full scale, but you are not restricted to
these loads.
• “
TYPE= 5 POINT CAL
” means 5-Point Known Load Calibration. You are prompted
to apply the loads to the transducer that were entered in the “
KNOWN POINT 1/5
”,
“
KNOWN POINT 2/5
”, “
KNOWN POINT 3/5
”, “
KNOWN POINT 4/5
” and “
KNOWN POINT 5/5
” regis-
ters. This technique can be used to compensate for the non-linearity in the
transducer. The usual loads used are zero scale, one-quarter scale, half
scale, three-quarters scale and full scale, but you are not restricted to these
loads.
The selection of the calibration type affects what menu items appear in the
CALI-
BRATION DATA
sub-menu.
