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.

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

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. 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.

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”.

View/print saved data

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.

Selection	Description
View Data	View all measurement data
View Statistics	The highest value, the lowest value and the average of all saved values are displayed here.
Print Data	The saved measurement data is printed here.
Clear All Data	Deletes all measured values

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.

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.

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.

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.

Data Software

With the Data Software, the saved data can be transferred directly to a PC.

Button	Function
Offline	Click this button to disconnect from the meter.
Online	Click this button to connect to the meter.
Peak	Transfers all saved data that have been saved in the “SAVE” mode
Ave	Transfers all saved data that have been saved in “AVE” mode
Clear	Clears the text field (does not clear the memory)
Save	Saves the text field in TXT format

Graph Software

The Graph Software enables a live display of all data on the PC. When you open the programme, you first see a list of graphs in the colours you have set.

Button	Function
Add	Add a layout
Modify	Change a layout
Del	Delete a layout
Run	Starts the layout

When you create or edit a layout, the following window appears. Here you can change the name and set the colours as required. After you have selected your layout, the following window opens:

Button	Function
Start	Starts the recording in the software
Stop	Stops the recording in the software
Offline	Disconnects from the meter
Online	Establishes a connection to the meter
Clear	Deletes all displayed values
UNIT	Switches the unit
Zero	Resets the zero point

To save the displayed data, right-click on the graph. Here you can export the graph and also import it again. The data can also be exported in TXT format via “Data output”.
Important: The exported graph can only be displayed again via the software.

More settings

You can access further settings for the meter by pressing the “Menu” key three times. This will take you to the “Other Settings” menu page.

Function	Description
Save Load	Here you can set the minimum value that must be reached so that the measured value is saved.
Start Finish Point	Here you can set which memory item is to be used for saving or printing, for example.
Shutoff	Here you can set the time for automatic power-off.

Warranty

You can read our warranty terms in our General Business Terms which you can find here: https://www.pce-instruments.com/english/terms.

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 re-use 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.
