Test:
"Test" serves to test the transducer. It outputs its maximum signal, the full scale value for the transducer is displayed on
the screen. However, this test cannot be performed in the peak measuring mode with counter-clockwise rotation! The
“On/Off
”
button is also available.
The "Return" key serves to return to the previous a level in the menu. Typically, to return to normal operation this key
must be pressed a number of times. If you are in normal operation when you press the "Return" key, you will return to
password level 0.
4.3 Measure menu
For direct and fast changeover of the peak, track, torque wrench or speed measurement modes without having to program a
parameter set. Parameter set "0" is selected automatically! Parameter set "0" contains the settings for the current parameter
set.
Notes:
− This menu is only suited for determining screwing parameters. Measured values and parameters cannot be saved!
Finally, you should create a new parameter set with these settings. See sec. 9.7, page 23
− A power-operated screwdriver cannot be switched off during tracking measurements!
− For torque wrench measurements the yielding moment should be at least 2% of the transducer full scale value.
4.4 Menu: Delete measured value
Menu path: Menu-> MVclear ...
See also sec. 11.5, page 29
4.5 Menu: Output
Measured values and parameter sets can be either displayed on the screen (see secs 11.4 and 9.4) or printed out through the
serial interface (see secs 12 and 9.5). Alternatively they can be uploaded to a computer .
In “Menu -> Output-> Display-> Light” the LCD display illumination can be switched on/off and in “Menu -> Output->
Display-> Contrast” the display contrast can be set manually.
4.6 Parameter menu
4.6.1 Transducer
Menu path: Menu-> Param-> Transducer
This menu allows the values for the torque transducer to be set directly in the test phase (parameter set no. 0). It subdivides
into "Full scale value", "Angle" and "Type" or “Sig./Ua” and “Zeroadjust”.
• The full scale value is set with the Entry editor (see Sec. 8.4).
• The "Angle" menu can be used to define whether the transducer used allows an angle measurement.
Angle decoders with 360 pulses per revolution are supported in this version.
The limits must be entered to display the angle on the screen! (Menu-> Parameter-> Limit-> Angle)
Note:
Angle measurement is only available in the software version with suffix "W".
• Different inputs for different transducer types can be selected in the "Type" / “Sig./Ua” menu depending on the
configuration level of the unit. GMV2-K is equipped with an active input as standard. A passive input and a digital
input are available as an option. If the type is selected, the transducer output signal can be entered in volts or mV/V.
•
Automatic tracking of zero-point drift can be enabled/disabled in the “zero” menu.
