INSTRUMENT CALIBRATION
2.1 Calibration Overview
There are two ways to calibrate the instrument:
1. Live calibration: You will be calibrating an actual load sensor to the instrument using live test
loads. You can have up to seven positive calibration points and up to seven negative calibration
points. These calibration points are denoted as C1 through C7. The absolute value of each
subsequent calibration point should be higher than the last, e.g., the C2 value should be greater
than the C1 value, etc.
2. Polynomial Equations1: You will be entering B coefficients from a calibration report. You can enter
up to four positive B coefficients and up to four negative B coefficients. These B coefficients are
denoted as B0 through B3. This must be used in conjunction with a reference calibration using a
calibrator. See G16 and G17 for reference calibration instructions.
Note: to disable PFx-F15 or PFx-F17, simply enter a zero value (e.g., “0.0”) for C1.
2.2 Live Calibration Overview
Live calibration comprises two main steps: zero calibration (PFx-F16) and span calibration (PFx-F17).
However, a third calibration for negative span (PFx-F15) is also available for systems operating in both
tension and compression.
Here is the recommended sequence for multiple fixtures and multiple calibration points:
1. Put force sensor onto test fixture
2. Go to PFx-F17 and press the down key; indicator prompts for the first calibration point
3. key in number 111111 and press the PEAK key; indicator will show “FIT” momentarily and then
automatically record the fixture reference point
4. Follow the PFx-F17 procedure as written for up to seven calibration points
5. If necessary, repeat these steps for negative span calibration (PFx-F15)
6. Mount the force sensor onto the final fixture
7. Go to PFx-F16 and perform zero calibration
2.3 Live Span Calibration Instructions (PFx-F17)
1. While in the Setup mode, scroll to " PFx-F17 ", and then scroll down once using the
ZERO (down) key. The instrument will briefly display ‘C 1’ and then prompt you to enter the data
for the first calibration point (C1). The previously saved force value will be displayed with one digit
blinking.
1Force (lbf) = B₀+ B₁R + B₂R² + B₃R³

Instruction Manual PM-5947 Copyright © 2022
2. Use the four directional keys to adjust the displayed value to 111111 and press the PEAK (set)
key; instrument will show “FIT” momentarily and then automatically record the fixture reference
point. The previously saved force value will be displayed with one digit blinking.
3. Place the first test load onto the force sensor.
4. Use the four directional keys to enter in the actual positive force value, e.g., 1000.0 lbf.
Increase the flashing digit by pressing the UNITS key. Decrease the flashing digit by pressing the
ZERO key. Pressing the PROFILE key or the DATA key will change the position of the flashing
digit.
5. Press the PEAK (set) key to save the value. The indicator briefly displays ‘End C1’ and then
moves to the next calibration point (C2).
6. Repeat steps 3 through 5 to enter data for the remainder of the calibration points. You need not
enter data for all seven calibration points. To cease entering additional calibration points,
simply enter zero for the new value, e.g., 0.0 lbf.
7. At the conclusion of C7 (or the last calibration point), the instrument will show “-donE” and reverts
to the top setup menu level, i.e.: “-F-”.
If the calibration was not successful, one of the following error messages will appear.
• "Err0" - The calibration test load or the keyed-in load is larger than the full capacity of the
instrument. Change the calibration test load or check the input data.
• "Err1" - The calibration test load or the keyed-in load is smaller than 1% of the full capacity of the
instrument. Change the calibration test load or check the input data.
• "Err2" – There is not enough signal from the force sensor to complete the calibration process.
Most common causes include incorrect force sensor wiring, a mechanical obstruction or a faulty
(damaged) force sensor.
Take the indicated action to correct the problem, and then perform a new calibration.
2.4 Live Negative Span Calibration Instructions (PFx-F15)
For negative calibration data, you will not see a minus sign on the screen. You need not be concerned as
all data entered is presumed to be a negative value, e.g., 1000.0 lbf is really
-1000.0 lbf.
1. While in the Setup mode, scroll to " PFx-F15", and then scroll down once using the
ZERO (down) key. The indicator will briefly display ‘C 1’ and then prompt you to enter the data for
the first calibration point (C1). The previously saved force value will be displayed with one digit
blinking.
2. Use the four directional keys to adjust the displayed value to 111111 and press the
PEAK (set) key; indicator will show “FIT” momentarily and then automatically record the fixture
reference point. The previously saved force value will be displayed with one digit blinking.
3. Place the first test load onto the force sensor.

4. Use the four directional keys to the actual positive force value, e.g., 1000.0 lbf. Increase the
flashing digit by pressing the UNITS key. Decrease the flashing digit by pressing the ZERO key.
Pressing the PROFILE key or the DATA key will change the position of the flashing digit.
5. Press the PEAK (set) key to save the value. The indicator briefly displays ‘End C1’ and then
moves to the next negative calibration point (C2).
6. Repeat steps 3 through 5 to enter data for the remainder of the calibration points. You need not
enter data for all seven calibration points. To cease entering additional calibration points,
simply enter zero for the new value, e.g., 0.0 lbf.
7. At the conclusion of C7 (or the last calibration point), the instrument will show “-donE” and reverts
to the top setup menu level, i.e.: “-F-”.
2.5 Live Calibration - Zero Instructions (PFx-F16)
1. While in the Setup mode, scroll to " PFx-F16", and then scroll down once using the
ZERO (down) key. The display will momentarily show "C 0" followed by a value. This value is the
internal A/D count and can prove useful when trying to troubleshoot setup problems.
2. Mount the force sensor onto the final fixture, assure a no-load condition and then press the PEAK
(set) key to save the zero-point value. The display will show “SET” and "EndC0" momentarily,
and then revert up to PFx-F16.
2.6 Entering B coefficient values for Compression Negative Span (PFx-CBx)
The B coefficient values for Compression Negative Span are entered one at a time in the “P” menu, using
two separate screens (pages). This example sets CB0 [B0 Compression Negative Span] to -
1.210034E+03 using the PF1-CB0 menu. All other menus [PF1-CB1, PF1-CB2 and PF1-CB3] operate
the same way.
Example: B0 = -1.210034E+03,
Page1: [1].[2][1][0][0][3][4] (B coefficient value)
Page2: [- ] [ ][ ] [E][P][0][3] (sign convention and exponent)
1. While in the Setup mode, scroll to " PF1-CB0 ", and then scroll down once using the
ZERO (down) key. The instrument will briefly display ‘1 of 2’ and then prompt you to enter the B
coefficient value. The previously saved B coefficient value will be displayed with one digit blinking.
2. Use the four directional keys to adjust the displayed value to the proper B0 coefficient value and
press the PEAK (set) key. The instrument will briefly display ‘2 of 2’ and then prompt you to enter
the sign convention and exponent value. The previously saved sign convention and exponent
value will be displayed with one digit blinking.
3. Use the four directional keys to adjust the displayed value to the proper sign convention and
exponent value and press the PEAK (set) key. The instrument will briefly display ‘SET’ and revert
to the PF1-CB0 menu level.
4. Repeat steps 1 through 3 as needed for the other Compression Negative Span B coefficient
values.

ADVANCED OPERATION
3.1 Peak Hold Mode
This mode is used to capture and hold peak forces recorded during a specific process. The most common
application is evaluating the breaking point of a part or assembly. The instrument records both positive
and negative peak forces.
This mode of operation is enabled by changing the F30 parameter setting to “5”.
1. Push the PEAK key to activate positive peak mode; the instrument briefly displays “HoLd P” and
then the “P” annunciator turns ON.
2. Apply force to the item under test. The display indicates and holds the positive peak force
applied.
