Thank you!
Thank you for purchasing a Mark-10 Series CT Torque Tester.
We are confident that you will get many years of service from
this product.
The CT can be used to test a number of different closure shapes
and sizes, along with other types of samples. To maintain nor-
mal functioning of the tester, avoid repetitive overloads and
shock loads.
We hope that this User’s Guide will provide a comprehensive
explanation of the CT’s operation and sufficient detail on its
specifications. However, if you have any other questions or con-
cerns, our technical support and engineering teams will be ea-
ger to help you.
Thank you again for your purchase and happy testing!

Series CT Closure Torque Testers
UNPACKING AND SETTING UP
1. Carefully unpack the CT and check for any damage. Inspect the contents to
ensure that you have received a tester complete with all accessories – see
“List of included items” below.
2. Place the tester on a firm, flat and level working surface free from vibration. If
preferred, the CT can be secured to a work bench with screws through the
four tapped holes in the underside of the base. Then insert the posts into the
desired holes on the sliders (see Fig. 1).
LIST OF INCLUDED ITEMS
OPTIONAL ITEMS
CT001 sample gripping jaws
These jaws are designed for use with square
or other shaped containers, in addition to
round samples. The jaws are reversible; one
side has a V-groove, while the other side is
flat. These jaws can be mounted to the inside
of the sliders, or the outside.
Quantity Item
1 Series CT Torque Tester
1 User’s guide (this booklet)
4 Sample gripping posts
2 Sample gripping jaws (optional)
1 AC adapter
CTRS data outputs package
(RS-232 & Mitutoyo)
This features allows torque data to be trans-
ferred to a PC, printer, or other device for
data analysis. The package consists of a
serial connector and data button to manually
output data. For more automated data collec-
tion, common software programs such as
WinWedge (available from Mark-10) can be
configured to automatically request data from
the CT.

CONTROLS
Series CT Torque Testers have four keys for controlling all functions:
POWER Turns power on and off. Also used to select configuration
menu items.
PEAK Used to select Clockwise Peak, Counterclockwise Peak
or Normal (real time) display mode. The actual peak read-
ings are always captured and can be recalled at any time.
Also used to step through configuration menu items.
ZERO Zeros any tare value (up to the full capacity of the gauge)
and clears the peak readings stored in memory.
DATA (OPTIONAL) Used to manually output the torque data point currently
displayed.
DISPLAY
The display consists of a 4 1/2-digit section and several indicators. Their func-
tions are listed below.
LO BAT Low battery voltage indicator
CW Clockwise torque indicator
CCW Counterclockwise torque indicator
CW PEAK Peak clockwise indicator
CCW PEAK Peak counterclockwise indicator
OZIN, LBIN, Units of measurement (model dependent)

POWER
The tester can be operated by the included 9V non-rechargeable battery or by
the included AC adapter. Battery life is approximately 30 hours. Do not use
adapters other than supplied or instrument damage may occur.
There are three levels of low battery voltage indication. At the first level the dis-
play shows a steady "LO BAT" indicating approximately one hour of charge re-
maining. The second level is indicated by a flashing "LO BAT" indicator. At the
third level the whole display except the "LO BAT" indicator will flash for three
seconds after which time the instrument will turn itself off. This prevents the in-
strument from working at voltages too low for reliable operation.
To access the battery, loosen the four screws on the bottom plate.
SETTING UP THE SAMPLE
Place the sample between the posts or jaws of the tester, and tighten, using the
knob. Posts can be placed in any of the holes on the sliders (see Figs. 1 & 2
below). Ensure that the sample is gripped firmly, however, excessive tightening
of thin-walled closures may result in sample deformation, possibly affecting test
results. When the sample is secured, gradually exert torque by hand. Sudden
torque application may produce incorrect readings.

Posts can easily be moved between
holes

CONFIGURATION
Series CT torque testers have several features with programmable options
allowing many user-specified choices. To enter the configuration menu, perform
the following:
1. Turn off the tester
2. Press and hold PEAK
3. Turn on the tester
4. Release PEAK
The version number of the internal software will be displayed for a short time
followed by either 'AoFF' for a standard CT or '232' if equipped with CTRS com-
munication option. The following secondary functions of keys are used during
the configuration process:
POWER Used to select a menu choice
PEAK Used to step through menu choices
NOTE: Once the menu has been entered, it can only be exited if changes have
been made.
The following list shows all configuration options. Italics indicate factory set-
tings.

CALIBRATION
To properly calibrate the CT, application of a precise torque value equal to the
full capacity of the tester in lbin (regardless of the displayed units) will be re-
quired.
While holding PEAK, turn on power to the tester. When ‘CAL’ appears on the
display, press POWER three times to select the calibration mode. At the ‘null’
prompt, press ZERO. At the ‘SPAn’ prompt, apply the calibration torque and
press POWER. The display will show ‘uuuu’ or ‘nnnn’ if the calibration torque is
insufficient or excessive, respectively. If this happens, the only way to terminate
the calibration mode is by momentarily disconnecting the battery or connecting
the AC adapter to the tester without plugging the other end into a wall outlet.
This will stop the calibration procedure without making any changes to the previ-
ous calibration data.
Successful calibration is indicated by ‘donE’ on the display. Press POWER to
save the changes and resume normal operation.

OUTPUTS
Outputs are available as part of the CTRS communication option. If installed, it
offers RS-232 and Mitutoyo BCD outputs on the 9-pin male connector. Please
refer to the pin diagram below for proper connection.
RS-232
The data transmission can be initiated by pressing the DATA button or by an
external device by sending ASCII "?" to the gauge. The gauge will respond by
sending the current reading in either full or numeric format, depending on the
configuration setting (see Section 3). Polarity sign indicates CW (+) or CCW (-)
torque. The transmitted string has the following format:
[POLARITY (SPACE OR -)][DATA][SPACE][UNITS (IF ENABLED)][CRLF]
Mitutoyo BCD
This output is useful for connection to data collectors, printers, multiplexers or
any other device capable of accepting Mitutoyo BCD data. The transmission is
initiated by the DATA button (see Section 3 about settings) or by the receiving
device.
