The CAPTEST Digital Torque Tester
CAPTEST is used to measure and record the torque required
for the opening and closing of screw-caps. CAPTEST stores
up to 240 readings. The stored data can be sent to the display
or to a data printer (e.g. EPSON P40) connected to the serial
RS232 port. Statistical evaluation is accomplished by means
of a Mitutoyo statistics processor (e.g. Mitutoyo DP-1 VR),
which interfaces directly with CAPTEST.
The splash-proof, stainless steel housing and the robust
construction of the clamping fixture guarantee continuous
and reliable operation in laboratory and tough production
environments.
The built-in rechargeable battery, in combination with the
latest power-saving technology, enables extended operation,
independent of a mains supply. In continuous operation, a
minimum 72 hours operating time can be achieved.
Automatic shut-off occurs if the device is not used for a
period of about 2 minutes, enabling the device to operate for
days without charging. When the battery charge is low, the
display will show ‘BAT’. The battery is prevented from being
low-level discharged by a security function that switches the
device off automatically.
When performing a measurement, the peak value of the
applied torque is displayed.

General Operating Instructions
Before using
On delivery, please check your CAPTEST for damage and
completeness. Should there be any defects, inform your
CAPTEST distributor immediately.
Screw the vertical grips into the clamping fixture, ensuring
a centred and symmetrical arrangement.
Charge the internal battery with the mains adapter
provided: connect the charger to the CAPTEST before
plugging it in.
The device can be operated with the mains adapter connected.
Battery management
CAPTEST is equipped with a modern power-saving
technique to achieve a relatively long operating time. If you
don’t use the device for a period of 2 minutes, it will switch
off automatically. To take new measurements, press the ON
key; CAPTEST is immediately ready to use. The readings
remain stored if the device is switched off manually or
automatically. When the maximum operating time is
reached, the symbol ‘BAT’is displayed. Please charge your
CAPTEST as soon as possible as described above. If you
continue using the device without loading, it will switch off
automatically shortly afterwards in order to prevent the
battery from low-level discharge.
Interfaces
The interface plug is placed at the rear of the device. An
RS232C or a DIGIMATIC cable can be connected. Be sure

4 Mecmesin CAPTEST Operator Manual
that both the device to be connected and your CAPTEST are
switched off before connecting.
RS-232 protocol: 9600 baud, 8 bit, 1 stop-bit, no parity, no handshake
Overload
CAPTEST is overload-protected by a mechanical end stop.
This protection prevents the internal sensor from being
damaged. The scale range, however, does not extend to this
load range. If the scale range is exceeded, ‘oL’(overload) is
displayed.
Maintenance, cleaning, repair
CAPTEST is largely maintenance-free. The spindle drive of
the clamping fixture has to be greased occasionally. Please
clean the parts with a soft, moistened cloth and don’t use any
strong cleansing agents or solvents. Repairs will only be
done by the manufacturer. If a repair is required, please
return your CAPTEST to your distributor and describe any
damage or faults you have identified.
Calibration
CAPTEST is calibrated carefully, so the precision of the
measurement will be guaranteed for one year. After that time
it is recommended to have the device checked annually by
the manufacturer.
You can also have the device recalibrated and certified. If
you do your own calibration, it is done in the following way:
switch the device off
press and hold the ZERO key
press the ON key while holding the ZERO key

CAPTEST Operator Manual Mecmesin 5
The device is now in the ‘continuous’mode and the actual
applied torque is displayed in the scientific unit N.m,
together with the tilde ‘~’. Now you can apply a well-known
torque and check the reading.
Safety issues
CAPTEST works with low-level voltages. In normal use
there is no risk of electric shock. The splashproof housing
normally prevents fluids from penetrating, but it should not
be exposed to jets of water or immersed, or the electronics
may be damaged. If you suspect any penetration of fluid,
send the device to your CAPTEST distributor.
Important
Be careful if the device is connected to the mains supply. The mains
adapter/charger is not splashproof. In case of a penetration of fluid
into the adapter there is a danger of electric shock with risk to your
personal safety.
Waste disposal
CAPTEST works with NiMh-battery. This battery must not
be put into normal waste, but should be taken to battery
recycling.

8 Mecmesin CAPTEST Operator Manual
Using a Mitutoyo Mini-Processor
The example used here is the Mitutoyo DP-1 VR, but other
Mitutoyo mini-processors may be used.
The DP-1 VR mini-processor is an easy-to-use instrument for
data analysis and statistical evaluation of CAPTEST data.
The integral printer documents both the CAPTEST data and
the results of analysis.
Before using the equipment, please read the DP-1 VR
operating instructions. Some aspects of operation with
CAPTEST will differ.
The DP-1 VR [DATA] key is disabled. CAPTEST sends the
data to the DP-1 VR: ON > ZERO.
Time-controlled data acquisition by DP-1 VR is not
possible.
Connection and use
Ensure that both the CAPTEST and DP-1 VR are switched off.
Connect the CAPTEST to the DP-1 VR with the enclosed
special Mitutoyo printer cable.
First switch on the DP-1 VR [Power] and then the
CAPTEST (ON key).
To clear any stored DP-1 VR data, press the [CL] key.
After you have taken a measurement, you can send
CAPTEST data to DP-1 VR by pressing the ON key; data
will be stored simultaneously in the CAPTEST and the
DP-1 VR, so it is not necessary to transmit complete
CAPTEST data to DP-1 VR at the end of a batch for the
purpose of later analysis.

CAPTEST Operator Manual Mecmesin 9
Note: If you do not want to print CAPTEST data each time it
is sent, but only to have statistical analysis data at the end of
a test batch, disable printing using the [Printer] key.
CAPTEST data will still be stored.
Switching off
Always switch the CAPTEST off first, and then the DP-1 VR.
This is important, because CAPTEST is equipped with an
automatic interface detection.
Detach the interface connection only if both the CAPTEST
and DP-1VR are switched off.
Setting tolerance limits
Clear stored data: press the DP-1 VR [CL] key and clear
the CAPTEST memory: ON > ON > ZERO.
Press [TOL. LIMIT] on the DP-1 VR to begin setting values.
Apply torque to the CAPTEST; to the upper or lower limit
required (sequence does not matter). Transmit the value to
the DP-1 VR: ON > ZERO.
Repeat the last step to the second limit torque.
Press the [TOL. LIMIT] key of the DP-1 VR. This will
complete the setting and print the tolerance limits:
LSL=lower limit; USL=upper limit, TOL=tolerance range.
For each measurement transmitted to the DP-1 VR, red
and green indicator lights will show if the result is below
the lower limit, above the upper limit, or within limits.
When you have completed a batch of measurements, make
sure the printer is on and press the DP-1 VR [STAT] key to
print the data values and histogram.
