5 Measuring modes

This torque meter has four different measuring modes. If the measured value is outside the
measurement range, "OVER" is shown on the display and an acoustic signal is generated. Only
when the measured value is back within the measurement range, a normal measurement can be
resumed.
To switch between the modes, press the "MODE" key in the current measuring mode. The current
measuring mode is displayed below the measured value.

5.1 Real Time

In Real Time (RT) measuring mode, the current measured value is continuously displayed.

5.2 Peak

In peak mode (PK), the highest measured value is displayed and held. This measuring mode can
be used for tensile and compressive force. The peak value can be reset with the "Zero" key.

5.3 Average Mode

In Average (AVG) mode, the average value of a measurement is displayed. There are two
different functions in this measurement mode.
MOD1: With this function, the average value of the force curve is displayed starting from the set
minimum force and over the set period of time.

MOD2: This function calculates the average above the set minimum measured value. When the
measured value falls below the set minimum value again, the measurement is finished. This
measuring procedure is possible over a period of 10 minutes. As long as the measuring time of
10 minutes is not exceeded, this measurement can be resumed at any time.

To make settings for this measuring mode, press the "Menu" key twice.

Setting

Meaning

Start Load

Here you set the force at which the average measurement should start.

Initial Delay

Here you enter the time span at the beginning of the measurement that is
not to be taken into account in the average measurement. Available
settings: 0.0 ... 300.0 seconds. Resolution 0.1 seconds. This parameter
only affects the MOD1 function.

Averaging Time

Here you set the measuring time for the average measurement. Available
settings: 0.0 ... 300.0 seconds. Resolution 0.1 seconds. This parameter
only affects the MOD1 function.

Average Mode

Here you select between the MOD1 and MOD2 function.

To select a parameter, use the arrow keys. Press the "Enter" key to select a parameter. Use the
arrow keys again to change the parameter properties. Press the "Enter" key again to apply the
settings you have made.

5.3.1 Measuring procedure

When "WAIT" is displayed on the screen, the meter waits until the set minimum load is applied.

When "DELAY" is shown on the display, the force gauge will wait until the set minimum time has
elapsed.

© PCE Instruments

7

When the minimum load is present and the minimum time has elapsed, the actual measurement
begins. “AVE..." appears on the display. The measurement is made. During this measurement, it
is not possible to see the current measured value.

When the measurement is completed, the display shows "DONE". You will then see the average
reading.

To reset the average value to start a new measurement, press the "Zero" key. The measured
value is saved at the same time. Up to 10 average values can be saved.

5.4 Save Mode

In "SAVE Mode", the highest measured values can be saved in a single measurement run. In the
memory, you can save 100 measured values (memory item number 00 ... 99). The number of
memory items used is displayed to the left of "SAVE". As soon as a single measurement run is
completed, the highest measurement value is automatically saved. It is recommended to
permanently save the measurement data on an external PC as the measurement values saved
in the meter could be lost.
You can set the minimum load for this function in the settings under "Save Load". This can be
found on the third menu page "OTHER SETTINGS".

To evaluate the saved data, press the "DATA" key. Then select "Save Mode Data" for the data
saved in "SAVE" mode or "Average Mode Data" to view the data saved in "AVE" mode.

Under "View Data", the memory item number, the direction of
rotation and the measured value are displayed. You can now
select a measured value with the arrow keys. To switch
between the individual pages, press the "Menu" key. To delete
a single measured value, press and release the "DEL" key
once.

The highest value, the lowest value and the average of all
saved values are displayed here.

7 Alarm limits

The alarm limits function is useful, for example, to check during quality control whether the tested
item is working within the specified tolerances. Two limits can be set here. If the measured value
is lower than the set "Lower Limit", this is indicated by the red and green LEDs lighting up. If the
measured value lies between the set "Higher Limit" and the set "Lower Limit", only the green LED
lights up. If the "Higher Limit" is also exceeded, only the red LED lights up.

Note: This function is only available in the measurement modes RT, PK and Save.

Display

Meaning

H. Limit

Highest limit value clockwise

L. Limit

Lowest limit value clockwise

H. Limit

Highest limit value counterclockwise

L. Limit

Lowest limit value counterclockwise

Now use the arrow keys to select the desired parameter. Press the "Enter" key to make
changes to this value. You can then change the value as desired with the arrow keys. Confirm
the entry with the "Enter" key. Press the "ESC" key to return to measuring mode.
Note: The second limit value must always be higher than the first set limit value. The set values
are shown above the reading in measuring mode.

8 Communication of interface and output interface

There are two different softwares for the torque meter. Both do not need to be installed. If the
computer does not find the correct drivers, you will find them in the installation folder.
With the Data Software, the memory can be read out and processed. With the Graph Software,
the current measured values can be transferred live to a PC and transmitted both graphically and
in tabular form.

If you have any questions, suggestions or technical problems, please do not hesitate to contact

us. You will find the relevant contact information at the end of this user manual.

11 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European
Parliament applies. Due to the contained pollutants, batteries must not be disposed of as
household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re­use them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance
with your local waste regulations.

If you have any questions, please contact PCE Instruments.
