Calibration procedure for MKP - PKP
c) Set the calibrator to 275.00
Ω
. The read-out must be "
∀ ∀ ∀ ∀ ∀.
2 2166"
+ 10 counts.
d) Push FUNC pushbutton, the instrument will go to the next
calibration group.
4) "ñ.I.ñA" - MAIN INPUT CALIBRATION - mA INPUT
The upper display will show "ñ.I.ñA".
4.1) "Lr" - INITIAL SCALE VALUE
The lower display will show "Lr"
a) Made the specific hardware setting as described at paragraph 2.
b) Connect the instrument under test to the calibrator as shown in
Fig. 10.

c) The upper display will show "ñ.I.ñA", the lower display will show
"Lr" while "OFF" will appear on the middle display.
d) Set calibrator to 0.000 mA.
e) Push
▲ pushbutton, the middle display will change to "On".
f) After a few seconds, start the calibration by pushing FUNC
pushbutton. At the end of this calibration routine, the instrument
will go to the next step.
4.2) "Hr" - FINAL SCALE VALUE
The upper display will show "ñ.I.ñA", the lower display will show
"Hr" while "OFF" will appear on the middle display.
a) Set the calibrator to 20.000 mA.
b) Push
▲ pushbutton, the middle display will change to "On".
d) After a few seconds, start the calibration by pushing FUNC
pushbutton. At the end of this calibration routine, the instrument
will go to the next step.
4.3) " ∀. ∀. ∀. ∀. ∀. " - mA INPUT CHECK
The lower and the middle display show "
∀ ∀ ∀ ∀ ∀.
" followed by the measured
value in counts (see fig 6).
The "ñ.I.ñA" "Hr" calibration is correct if the indication is equal to " ∀ ∀ ∀ ∀ ∀. 3
0000" + 10 counts.
a) Check the zero calibration, by setting the calibrator to 0.000 mA,
the read-out must be equal to "
∀ ∀ ∀ ∀ ∀.
0 0000" + 10 counts.
b) Check the linearity by setting the calibrator to 10.000 mA The
read-out must be "
∀ ∀ ∀ ∀ ∀.
1 5000" + 10 counts.
NOTE: when it is desired to use a different check point, the
following formula describes the ratio between the signal input and
the instrument read-out (in counts).
Instrument readout (in counts) =
input value

c) Push FUNC pushbutton, the instrument will go to the next
calibration group.
5) "ñ.I.5" - MAIN INPUT CALIBRATION - 5 V INPUT
The upper display will show "ñ.I.5".
5.1) "Lr" - INITIAL SCALE VALUE
The lower display will show "Lr"
a) Made the specific hardware setting as described at paragraph 2.
b) Connect the instrument under test to the calibrator as shown in
Fig. 5.
c) The upper display will show "ñ.I.5", the lower display will show
"Lr" while "OFF" will appear on the middle display.
d) Set calibrator to 0.000 V.
e) Push
▲ pushbutton, the middle display will change to "On".
f) After a few seconds, start the calibration by pushing FUNC
pushbutton. At the end of this calibration routine, the instrument
will go to the next step.
5.2) "Hr" - FINAL SCALE VALUE
The upper display will show "ñ.I.5", the lower display will show
"Hr" while "OFF" will appear on the middle display.
a) Set the calibrator to 5.000 V.
b) Push
▲ pushbutton, the middle display will change to "On".
d) After a few seconds, start the calibration by pushing FUNC
pushbutton. At the end of this calibration routine, the instrument
will go to the next step.
5.3) "
∀. ∀. ∀. ∀. ∀.
" - 5 V INPUT CHECK
The lower and the middle display show "
∀ ∀ ∀ ∀ ∀.
" followed by the measured
value in counts (see fig 6).
The "ñ.I.5" "Hr" calibration is correct if the indication is equal to " ∀ ∀ ∀ ∀ ∀.

0000" + 10 counts.
a) Check the zero calibration, by setting the calibrator to 0.0000 V, the
read-out must be equal to " ∀ ∀ ∀ ∀ ∀. 0 0000" + 10 counts.
b) Check the linearity by setting the calibrator to 2.500 V The read-
out must be " ∀ ∀ ∀ ∀ ∀. 1 5000" + 10 counts.
NOTE: when it is desired to use a different check point, the
following formula describes the ratio between the signal input and
the instrument read-out (in counts).
