13  Optional functions  

By keeping the power button pressed, the available hardware and software options, the time of day and the date will be 

displayed. See sec. 2.5, page 9. 

 

13.1  Battery operation 

The device is fitted with an optional battery. The device can run solely on battery power as the torque sensor will also be 

powered from the battery. 

The lead acid battery requires no maintenance, is protected against overcharging and is automatically recharged during 

permanent mains operation. It takes up to a maximum of 12 hours to completely recharge during normal measurement 

mode; when the device is switched off it takes up to a maximum of 5 hours to recharge the battery. The device can then run 

for at least 6 hours in continuous measurement mode. 

The GMV2-K has a battery monitoring feature. If the battery is almost completely discharged, the message “Recharge!” 

will be displayed every minute and a beep is sounded as well. The warning message appears permanently at the bottom of 

the screen on the right. You should recharge the battery then as soon as possible (you can now run the device with the 

mains cable).  

Note: 

 

If the battery charge is very low, the device will switch itself off and it cannot be switched on again. 

 

The device will function, however, if connected to the mains power system 

 

If the device is in storage or is unused over a longer period (1/2 year) the battery will have to be recharged. 
 

13.2  Passive input 

All passive measuring bridges with a resistance ≥ 350Ω and a signal of 0.5mV/V to 4mV/V can be connected to the device. 

The pin assignment for the socket is shown in Sec. 0, page 37 ff. 

 

13.3  Digital input 

You can connect the torque sensors fitted with digital output you receive from ETH with this option.  

They are connected to the active socket (ACT/DIG). 

 

13.4  Measured-value transmission GMV2-K 

PC 

13.4.1 Function 

The supplied EXCEL

® 

files (with program macros) are used for data transmission from GMV2-K to PC, for statistical data 

analysis, for archiving and printing out the data. Test logs can also be generated automatically. A sample log for torque 

wrenches is supplied with the system. You may add other logs, or adapt existing ones as you wish. 

The first page in the file contains the measurement table. 

The measured values can only be scanned in here.

 The other 

tables and diagrams access them.  

 

Important notes:

 

!

 

If an error message is displayed when you open the file,

 you should run the “Setup.Exe” program on the 

accompanying CD. 

!

 

Before transmission, ensure that “===> PC”  is set as printer on the GMV2-K  

(Menu-> Param-> Setting-> Program-> Printer-> “===> PC”), select baud rate with “+” and “-”. 

!

 

The existing pages should not be deleted or renamed! 

!

 

The programming of macros is restricted 

 

13.4.2 Menu bar 

An additional menu bar appears on the screen when the file is opened. This menu bar behaves like the other menu bars: it 

can be moved and faded in and out. You can select the number of the serial port being used from a list. The displayed baud 

rate must be the same as the baud rate selected in GMV2-K. We recommend using a baud rate of 4800. 

 

13.4.3 Data transmission 

The “Scan” button activates the RS-232 port and renders the PC ready to receive data. If the table already contains 

measured values, the system prompts you to enter whether you want to overwrite these measured values or keep them. In 

the latter case, the scanned measured values will be appended to the existing ones. The button then changes to “Finished?”.
