v. In the Connect To dialog box that pops up next, go to the drop down menu labeled
“Connect Using:” and select the serial port you connected the cable to in step 2. It
is most likely that you are connected to COM1.
vi. In the COMx Properties dialog box that pops up next, set the “Bits per second:” to
9600, the “Data bits:” to 8, the “Parity:” to None, the “Stop bits:” to 1 and the “Flow
Control:” to None.
vii. Click the Apply button and then click the OK button.
viii. You should now see tension values appearing in the Hyper Terminal window.
ix. To download the data log data: Go to: Transfer > Capture text… and enter the
name of the file that you wish to save the data to.
x. Next, click anywhere inside the Hyper Terminal window and then press ‘d’ on your
keyboard. The data should download from the instrument to the file that you chose.
xi. When you are finished collecting data, close Hyper Terminal.
xii. To save the data in Microsoft Excel format, use Microsoft Excel to open the file you
saved the data log to and save it as an Excel file.

UPLOADING LOGGED DATA
(Optional feature)
) via RS-232
,
SERIAL COMMUNICATIONS.
a. Refer to the previous section, Sec 4.15, Serial Data Collection (RS-232 option) and
configure communication protocols as outlined. Note: step c has no effect on
transferring stored data and can be adjusted to any setting.
b. To retrieve, or upload logged data from the instrument, send a lower case d.
c. Collected data will remain in memory, regardless if instrument is turned off, until
overwritten with new data.
FEATURES
Large, easy to read backlit, graphic display with adjustable backlighting and contrast.
Display shows tension, name of calibration selected, running line minimum and maximum
tension values, and battery charge level.
Select tension values to display in Grams, lb, Newtons, or cN.
Instruments come with calibrations for numerous wire and filament sizes.
Up to 10 additional custom calibrations may be programmed into instrument. (All calibrations
password protected.)
Choose your calibration by first highlighting and selecting the material (either wires, filaments, or
custom), then the units of measurement (inches, mm, AWG wire sizes, or custom). Lastly, select
the material size or gauge number and push “Enter”. The instrument automatically adjusts to the
calibration you’ve selected with a full-scale accuracy of +/- 1%. (Full-scale accuracy for custom
sizes is material specific.)
Selectable LCD refresh rates allow for stable digital readings.
Re-chargeable NIMH batteries and power supply provided. Approximately 9 hours of operation
per battery charge. Automatic shut-off after 10 minutes of non-use.
Instruments may be operated continuously while connected to power supply.
Numerous application-specific models available.
All instruments factory-calibrated and ready for use. Calibration certificate included. All
calibration values traceable to National Standards.
All models typically available from stock.

Follow the same procedure for each sequential letter or space of your new description. Continue
pressing
ENTER
until all spaces in the description have entered values. Once your new name has
been entered you will be returned to the

CALIBRATION OF SPEED
.
(
Optional feature)
From the Main Display press the
UP
and
DOWN
keys
until you reach
SETUP
.
Press
ENTER
.
Using the
UP
and
DOWN
keys select
CALIBRATE LENGTH
.
Press
ENTER
.
Next calibrate the speed function: Using a precise 20 foot length of your material
(20.0’), thread one end through the instrument’s three rollers and slowly pull exactly 20.0’ through
the instrument. (While you pull your 20’ length the instrument will count pulses on the display)
After pulling the 20’ length, press
ENTER
.
Your instrument speed calibration is now complete.
13.
MONITORING TENSION OR SPEED THROUGH THE ANALOG OUTPUT
(Optional feature)
. Output
values are: 0 – 5 VDC or 4 – 20 mA. Connect Analog Output Cable to receptacle located on the
bottom side of instrument. Connect output cable leads to the analog input of your measurement or
control device. The
RED
lead is V, the
WHITE
lead is mA, and the
BLACK
lead is ground.
From the main display use the
UP
and
DOWN

SERIAL DATA COLLECTION (RS-232 option).
Instruments outfitted with the optional RS-232 feature
(designated with a -E or –D in the part number) support serial communications as follows:
a. The baud rate is 9600 with no parity bit, 8 data bits, 1 stop bit (9600 8N1), and set “Flow
Control” to None.
b. Serial communications will work with most PCs with a cable up to 15 feet long.
c. Setting the dampening rate on the instrument to “1 Hz + Serial”, “2 Hz + Serial” or “5 Hz +
Serial” will cause the instrument to output the tension values at a rate of once, twice or five
times per second, respectively. The dampening rate can be set by going to the
SETUP
menu,
selecting
DAMPENING
, adjusting the value of the dampening rate with the
UP
and
DOWN
buttons and then pressing the
ENTER
button.
d. The units output serially will be the same units that are selected in the “Tension Units” menu.
The currently selected tension units (such as Grams or Newtons) are also displayed on the
main tension screen.
e. Perform the following steps in order to log serial data from the instrument using
Hyper Terminal on a PC and put it into a Microsoft Excel spreadsheet:
i. Ensure the that the dampening rate is set to “1 Hz + Serial”, “2 Hz + Serial” or
“5 Hz + Serial”.
ii. Connect the serial cable from the instrument to a serial port on your PC.
iii. Go to the Windows Start Menu and choose Programs->Accessories
>Communications->Hyper Terminal
iv. In the Connection Description, dialog box that pops up, type in a name for the new
connection (any name will work) and press the OK button.
