value will be held and displayed.
If the force measured exceeds the range of the meter, the display will indicate “¯ ¯ ¯ ¯ ¯ ¯ ¯ ¯ ¯” for tension or
“ˍ ˍ ˍ ˍ ˍ ˍ ˍ ˍ” for compression.
Press the BACKLIGHT button to turn the backlight ON. Press again to turn it OFF.
If the measured value exceeds the maximum range, the internal buzzer will sound a warning.
Press the display reverse button to invert the reading and provide readability in any position..
If the meter’s buttons freeze, press the RESET button on the bottom of to reset the CPU.
If auto power off is enabled in the setup mode, after 10 minutes of inactivity the meter will beep and
then shut down. This feature extends battery life.

Datalogger
Preparation for datalogger
1. Insert an SD card (from 1G size up to 16G, ≤ 4G recommended) into the SD card slot at the
bottom of the meter. The card must be inserted with the front of the card (label side) facing
toward the rear of the meter.
2. If the SD card is being used for the first time it is recommended that the card be formatted and
the logger’s clock set to allow for accurate date/time stamping during datalogging sessions.
Refer to the Setup Mode section for SD card formatting and time/date setting instructions.
3. European and USA numerical formats differ. The data on the SD card can be formatted for
either format. The meter defaults to USA mode where a decimal point is used to separate units
from tenths, i.e. 20.00. The European format uses a comma, i.e. 20,00. To change this setting,
refer to the Setup Mode section.
Automatic Datalogging
In automatic datalogging mode the meter takes and stores a reading at a user-specified sampling
rate onto an SD memory card. The meter defaults to a sampling rate of two seconds. To change the
sampling rate, refer to the Setup Mode section (the sampling rate cannot be ‘0’ for automatic
datalogging):
1. To begin an automatic Datalogging session, press and hold the LOGGER button for at least 2
seconds.
2. The meter will scan for an SD card and verify that it can be used to store data. If a card is not
inserted or if the card is defective, the meter will display a blinking ‘EMPTY”. In this case,
switch the meter OFF and try again with a valid SD card.
3. If the SD card is valid, the display will display a flashing “DATA RECORD” icon and the meter
will beep (if the beeper is enabled) each time reading is stored at the programmed sample rate.
4. To pause the datalogger, momentarily press the LOGGER button. The REC icon will stop
flashing. To resume logging momentarily press the LOGGER button again.
5. To end the datalogging session press and hold the LOG button for at least 2 seconds.
Manual Datalogging
In the manual mode, data is logged when the LOGGER button is pressed.
1. Set the sampling rate to ‘0’ seconds as described in the Setup Mode section.
2. Press and hold the LOG button for at least 2 seconds; the lower portion of the display will show
p-n (n = memory position number 1-99).
3. Press the LOGGER button momentarily to log a reading into memory. The “DATA RECORD”
icon will flash each time a data point is stored.
4. Use the ▲ and ▼ buttons to select one of the 99 data memory positions in which to record.
5. To exit the manual datalogging mode, press and hold the LOGGER button for at least 2
seconds.

Peak Hold Datalogging
1.
Power on the meter
2. Press the PEAK button. The display “PEAK” and “FAST” icons will appear.
3. Press the ZERO button to zero the display.
4.
Press the " LOGGER button. The LCD will indicate " DATA RECORD " at the programmed
peak hold sampling time, in milliseconds, will briefly appear on the bottom of the LCD. (for
example " 10 "). Now the meter is ready for the Peak Hold record mode ( Fast Datalogger
measurement )
5.
If a force is applied which is >1% of full capacity then measurements will be made and stored
at the sample rate.
6.
When the peak value is logged, the meter will exit the "DATA RECORD" mode and the peak
value will freeze on the Display
7.
On the bott om of the LCD the da ta record number will display and count down to zero. At the
same time, all the memory data will save into the SD memory card
Note: Peak measurements should be performed with the meter mounted on a stand.
Checking Time information
1.
Power on to the normal measurement mode
2. Press the TIME button and the lower display will indicate the Hour/Minute/Second.
3. Press TIME again and the lower display will indicate the Year/Month/Date.
4. Press TIME again to exit time information.
Checking Sampling Time information

SD Card File and Data structure
1. When an SD card is used for the first time a folder is created on the card and named FGA01.
Up to 99 spreadsheet documents (each with 30,000 readings) can be stored in this folder.
2. When datalogging begins a new spreadsheet document named FGA01001.xls is created on
the SD card in the FGA01 folder. The data recorded will be placed in the FGA01001.xls
document until 30,000 readings are reached.
3. If the measurement session exceeds 30,000 readings, a new document will be created
(FGA01002.xls) where another 30,000 readings can be stored. This method continues for up to
99 documents, after which another folder is created (FGA02) where another 99 spreadsheet
documents can be stored. This process continues in this same fashion with folders FGA03
through FGA10 (last allowable folder).
SD Data Card to PC Data Transfer
1. Complete a datalogging session as detailed in above in the previous sections. Hint: For the
first test, simply record a small amount of test data. This is to ensure that the datalogging
process is well understood before committing to critical datalogging.
2. With the meter switched OFF, remove the SD Card.
3. Plug the SD Card directly into a PC SD card reader. If the PC does not have an SD card slot,
use an SD card adaptor
4. Power the PC and run a spreadsheet software program. Open the saved documents in the
spreadsheet software program
