INSTRUMENT CALIBRATION
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.
2.  mV/V calibration: You will be calibrating the instrument using a load cell simulator (cal- ibrator). Previously established mV/V input signal values – and the corresponding force values – are required. You can have up to six positive calibration points and up to six negative calibration points. These calibration points are denoted as C1 through C6. 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.

Live Calibration Overview
Live calibration comprises two main steps: zero (F16) and span (F17). A third calibration menu for negative span (F15) is also available for systems operating in both tension and compres- sion.
What follows is the recommended live calibration sequence. Any deviations from this may cause unwanted behavior:

1.  Place the force sensor onto your test fixture, with no other forces applied.
2. Navigate to F17 (span calibration) and press the PEAK (down) key; indicator prompts for the first calibration point, C1.
3.  Key in number 111111 and press the ZERO (set) key; indicator will show “FIT” momentarily and then resume its prompt for the first calibration point, C1.
4. Follow the F17 procedure (see next section) for up to seven span calibration points.
5. Optional: repeat steps 2-4 for negative span calibration (F15)
6. Mount the force sensor onto its final fixture.
7.  Navigate to F16 and perform the zero calibration.

Notes:

1. You may see dashes appear temporarily on the screen during live calibration. This simply means that the instrument is processing data.
2. To disable the positive calibration slope, simply enter a zero value (e.g., “0.0”) for C1 while in F17.
3.  To disable the negative calibration slope, simply enter a zero value (e.g., “0.0”) for C1 while in F15.

Live Span Calibration Instructions (F17)

1. While in the Setup mode, scroll to “F 17”, and then scroll down once using the PEAK (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 ZERO (set) key; indicator will show “FIT” momentarily and then automatically record the fixture ref- erence point. The previously saved force value will be displayed with one digit blinking.
3. Apply the first test load to 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 press- ing the PEAK key. Pressing the DATA key or the ON/OFF key will change the position of the flashing digit.
5. Press the ZERO (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 ca- pacity 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 ob- struction or a faulty (damaged) force sensor.
  Take the indicated action to correct the problem, and then perform a new calibration. To save all calibration settings, you must exit all menus in the following manner: At the pa- rameter level, press the UNITS (up) key twice (two times) to exit the Setup Menu. The in- strument displays ‘SAvE’ and then automatically powers off.

Live Negative Span Calibration Instructions (F15)
For negative calibration data, you will not see a minus sign on the screen. You need not be con- cerned 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 “F 15”, and then scroll down once using the PEAK (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 dis- played with one digit blinking.
2.  Use the four directional keys to adjust the displayed value to 111111 and press the ZERO (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. Apply the first test load to 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 PEAK key. Pressing the DATA key or the ON/OFF key will change the position of the flashing digit.
5.  Press the ZERO (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 additionalcalibration 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-”.
   To save all calibration settings, you must exit all menus in the following manner: At the pa- rameter level, press the UNITS (up) key twice (two times) to exit the Setup Menu. The in- strument displays ‘SAvE’ and then automatically powers off.

Live Zero Calibration Instructions (F16)

1. While in the Setup mode, scroll to “F 16”, and then scroll down once using the PEAK (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. If you see an ‘N’ on the screen, this indicates that the displayed value is neg- ative (minus).

2.  Mount the force sensor onto its final fixture, assure a no-load condition and then press the PEAK key to zero the display reading. Do NOT skip this step!

3.  Quickly press the ZERO (set) key to save the zero-point value. The display will show “SET” and “EndC0” momentarily, and then revert up to F16.
   To save all calibration settings, you must exit all menus in the following manner: At the pa- rameter level, press the UNITS (up) key twice (two times) to exit the Setup Menu. The in- strument displays ‘SAvE’ and then automatically powers off.
   Underneath the display you may find down arrows which have been activated. For each down arrow displayed, add 1 million to the displayed count. (Max value is 4.8 million counts)

Key-in mV/V Calibration Instructions (F27)
You will be entering data for up to six positive calibration points and up to six negative calibra- tion points. These calibration points are denoted as C1 through C6. The absolute value of each subsequent calibration point should be higher than the last.
Each calibration point requires entry of two values:
A force value, e.g., 200 lbf
A corresponding mV/V input signal value, e.g., 1.0125 mV/V.

1. While in the Setup mode, scroll to “F 27”, and then scroll down once using the PEAK (down) key. The indicator will briefly display ‘Pos C’ and then prompt you to enter the data for the first positive calibration point (C1). The previously saved force value will be displayed with one digit blinking.
2.  Use the four directional keys to enter in the actual positive force value, e.g., 200 lbf.
3.  Press the ZERO (Set) key to save the force value. The indicator will prompt you to enter the corresponding mV/V input signal. The previously saved mV/V value will be dis- played with one digit blinking.
4.  Use the four directional keys to enter in the actual mV/V value.
5.  Press the ZERO (Set) key to save the mV/V value. The indicator briefly displays ‘End C1’ and then moves to the next positive calibration point (C2).
6.  Repeat steps 2 through 5 to enter data for the remainder of the positive calibration points. You need not enter data for all six positive calibration points. To cease en- tering additional calibration points, simply enter zero for both values, e.g., 0 lbf and 0.0000 mV/V.
7. The indicator will briefly display ‘Neg C’ and then prompt you to enter the data for the  first negative calibration point (C1). The previously saved force value will be displayedwith one digit blinking.
8.  Use the four directional keys to enter in the actual negative force value, e.g., 200 lbf. 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., 200 lbf is really -200 lbf.
9.  Press the ZERO (Set) key to save the force value. The indicator will prompt you to enter the corresponding mV/V input signal. The previously saved mV/V value will be dis- played with one digit blinking.
10.  Use the four directional keys to enter in the actual negative mV/V value. For negative  calibration data, you will not see a minus sign on the screen. You need not beconcerned as all data entered is presumed to be a negative value, e.g., 1.0125 mV/V is really -1.0125 mV/V.
11.  Press the ZERO (Set) key to save the value. The indicator briefly displays ‘End C1’ and then moves to the next negative calibration point (C2).
12.  Repeat steps 8 through 11 to enter data for the remainder of the negative calibration points. You need not enter data for all six negative calibration points. To cease en- tering additional calibration points, simply enter zero for both values, e.g., 0 lbf and 0.0000 mV/V.
13.   When all values are entered successfully, the display will show “End Cx” momentarily before reverting to F27.

To save all calibration settings, you must exit all menus in the following manner: At the pa- rameter level, press the UNITS (up) key twice (two times) to exit the Setup Menu. The in- strument displays ‘SAvE’ and then automatically powers off.

ADVANCED OPERATION

Peak Hold Mode
This mode is used to capture peak forces measured during a specific process. These peak force values are held (frozen) on the screen. A common application is determining the breaking point of a part or assembly. The instrument captures both positive and negative peak forces. Peak forces are not retained when the instrument is powered OFF.
This mode of operation is enabled at the Factory [the F30 parameter = “5”]. Use the F36 param- eter setting to select the default (power on) peak hold mode.

1. Push the PEAK key to activate the peak mode you want to use (repeat as needed):
   – “hoLd P” = Positive Peak; the “P” annunciator is ON.
   – “hoLd U” = Negative Peak; the “P” annunciator is ON
   – “LiVE” = Live Measurement (peak forces not captured); the “P” annunciator is OFF

2.  Apply force to the item under test. The measured peak force is displayed on the screen.

3. To reset all peak values to zero, press and hold the PEAK key for about 3 seconds un- til the display shows “Clr P”. This can be done in any peak hold mode.

SERIAL PORT INFORMATION

SERIAL PORT MODES
DEMAND DUPLEX MODE
The Demand Duplex Mode provides a two-way serial transmission mode. In this mode, the output information is transmitted on demand; either by pressing the DATA key on the instrument’s front panel or upon receiving a recognized command from a host de-
vice (i.e., computer).
NOTE: Ensure that your cabling has a crossover (null modem) and contains the proper handshaking lines.
