2.1 Important notes
If the unit is opened or dismounted within the warranty period the warranty will be rendered null and void.
The unit should only be opened by qualified staff.
Only cables designed for use with the unit may be connected to it. Damage caused by connecting incorrect cables are not
covered by the warranty.
In battery operation, operation of the electric screwdriver is not possible!
The unit is not grounded during battery operation. Should current-carrying equipment be connected to the unit they must be
grounded according to technical regulations.
The full scale value displayed on the screen must always correspond with the actual transducer being used.
Where there is a risk of injury to persons and damage to equipment, the user must take appropriate safety measures (for
example, use covers, overload protection devices) (relevant accident prevention regulations should be observed!).
Due to the use of surge arresters (Varistors) an Insulation measurement according VDE 701/702 is not possible.
Please use the substitute leakage current measurement method according VDE 701/702.
The unit is not approved for service in hazardous areas.

2.4 Connecting the torque transducer
Suitable connection cables are available for different types of torque transducers!
This standard GMV2-K unit has been designed for use with active transducers with a ± 1.25V to ± 10V signal. A
±0.5mV/V to ±4mV/V passive input and a digital input are available as an option. Please use the appropriate cable only
which can be obtained from ETH.
2.5 Switching on
You can switch the unit on with the button when you have checked that the cable has been correctly connected.
After a short self-test all settings valid before the unit was switched off are reloaded. The transducer is now zeroed. The
unit is then ready. If the error message "Charge!" appears now, please connect the power cable. You can now power the
unit from the mains or switch it off and let it charge for approximately five hours.
If you keep the key pressed while switching on the device, time of day, software version and the optional functions will be
displayed. The following abbreviations appear:
• V x.xx Software version
“-”
• ax Active input with adjustable input range
• px Passive input with adjustable input range
• d Digital input
“-”
• W Angle measurement
• T PC transfer
• E I/Os
• D Output for Digimatic printer
Notes:
− When the unit is being switched on the outputs are operated for a short period. The manual switch for the power-
operated screwdriver should therefore be switched off during power-up.
− Check before the first measurement that the initial settings for the unit (see Sec. 6) meet your requirements.
− If the battery is not charged fifteen minutes after the first charge message, the unit switches itself off.
When the calibration period for the GMV2-K has elapsed, the error message
“Error: Calibration date” appears when the device is switched on. In this case, please send the device to ETH.
2.6 Switching off
You can switch off the device with the button. If the power-saving function (standby) is enabled, the device switches
itself off if it unused for a set period. If, due to a fault, you cannot operate or switch off the unit, you can remove the fuse
from the rear (data may however be lost in this case).

3 What's new in software version V 5. 1 (after V4.1)
3.1 Dynamic repeat rate for keys
The keys (+, -, choose, etc.) now have a repeat function when pressed for longer periods.
The repeat rate increases continually.
3.2 Automatic conversion of the transducer full scale value to other units
When a transducer with integral chip is connected to the device, a unit that is different to the transducer unit may be
selected in the parameter set. The transducer full scale value is automatically converted to the selected unit. Only the
available units can now be used!
Example:
• Transducer with 10 Nm, selected unit “InLb” displayed full scale value: 88.51 Inlb
• Transducer wit 10 Nm, selected unit “Ncm” displayed full scale value: 1000 Ncm
Note:
• If, when programming a parameter set, a particular unit is not available, disconnect the transducer and then choose the
wanted unit.
3.3 Supporting transducers with two measuring ranges (option on request)
Transducers with two measuring ranges can now be connected to the active socket.
The small measuring range appears in the menu as “akt2rng, standard_range”.
The large measuring range appears in the menu as “akt2rng, high_range”.
Note:
• This is an optional function and is not available in all devices
• Select the “Standard_range” option for transducers with only one measuring range!
3.4 Improved support for a number of inputs
When the GMV2-K supports inputs for a number of transducer models, each of the available inputs can be selected as
required. The GMV2-K socket designation, the transducer model and, if applicable, the measuring range (stndrt / large)
will be displayed.
In addition, this information is also output when the parameter set is displayed or printed out.
Note:
• This is an optional function and is not available in all devices
3.5 Universal input range for the active and passive input
Menu path:
• “Menu -> Param -> ParSet -> Change -> Edit”
• “Menu -> Param -> Transducer -> “Model” or “Sig./Ua”
The inputs can be adjusted easily now to the output signal from most sensors. They can be programmed separately for each
parameter set. If a default value is available, it will be used without the system asking for confirmation. The correct value
can be entered for every parameter set with the setting “Enter” for Ua. This is how the calibration value is entered for
passive transducers.
Input range:
Active input: ±1.25V to ±10V in steps of 1mV, or 5V / 10V
Passive input: ±0.5mV/V to ±4mV/V in steps of 1µV/V, or 1mV/V / 2mV/V / 4mV/V
Note:
This is an optional feature and therefore not available in all devices

Nr.: 162e Operating Instructions GMV2-K revised: 09.05.2019 Rev.: 0
3.6 Adjustable overload range
Menu path:
• “Menu -> Param -> Param set -> Change -> Edit”
• “Menu -> Measure -> Overload
The measuring range can now be much larger than the nominal signal of the transducer. The overload range can be
programmed separately for each parameter set from 0% to 100% of the transducer end value – however, the resolution of
the displayed measurement is reduced in proportion to the selected overload range. Different values can be programmed by
selecting “Enter” in the defaults under overload range.
(Menu path: “Menu -> Param -> Setting -> Defaults -> Overload”).
Caution
• If the mechanical overload capability of the torque transducer is exceeded for even a short period, this will
immediately destroy the transducer!
3.7 Automatically tracking zero-point drift
The zero voltage on torque sensors varies slightly as a function of temperature: the zero-point drifts when the device is
switched on until the sensor reaches its operating temperature. In the zero-load condition, the system detects and tracks this
drift and compensates for it accordingly. The device continues to take correct measurements. When the tracking function
for zero-point drift is active, an “A” (Automatic) appears at the bottom of the screen.
3.8 Pulse-type screwdriver mode
This function is very similar to the peak measuring function: additionally, a correction factor is available in this mode, but
angle measurements cannot be taken.
3.9 Streamlining parameter set entry
3.9.1 Defaults
Menu path: “Menu -> Param -> Setting -> Defaults”
In “Defaults” either a fixed numerical value or “Enter” may be selected.
The desired value may be entered when programming a parameter set and when “Enter” is set.
When a fixed numerica l value is the default setting, it is automatically loaded without confirmation from the user
when a parameter set is programmed. This saves multiple data entries.
A default setting is available for each of the following:
- input sensitivity of the active and passive input
- overload range
- automatic tracking of zero-point drift
Examples:
• If you always use thread adapter transducers (DRFS..., DRFN...), select active - 5V
• If you always use laboratory transducers (DRL), select active - 10V
• Select passive, Enter for passive transducers
Note:
• Changes to the default setting do not immediately impact the current parameter set!
The default setting is not loaded until a parameter set is processed or programmed.
• Parameter sets that have already been programmed are not changed when defaults are changed.
3.9.2 Hiding unused funct ion s
Menu path: “Menu -> Param -> Setting -> Function”
Functions that are seldom used can be hidden, so that they are disabled (without user confirmation) when a parameter set is
programmed. The process of entering the parameter set is thus shortened.
The functions are always available in the direct parameter entry menu.: “Menu -> Measure ... / Parameter..”.

Nr.: 162e Operating Instructions GMV2-K revised: 09.05.2019 Rev.: 0
Example:
• The “Parameter set text, data record ID and operator number” menu can be hidden for all operating modes (“More”).
• Angle, speed and power measurement are disabled during tracking measurements.
Note:
• Changing the functions does not immediately impact the currently available parameter sets!
3.9.3 Correction factor
A correction factor may only be entered in the (new) operating mode “impulse wrench”
3.9.4 Filter for peak measuring
This function is no longer available in version V5.2!
3.10 Deleting measured values
Menu path: Menu -> MVclear...
The operator can now choose whether he wants to delete all measured values, the measured values in a parameter set, or
only single data records (see sec. 11.5, page 29).
3.11 Detecting new transducers and new measuring ranges
When ETH transducers that are equipped with a memory chip are used, the GMV2-K detects the removal and insertion of
the transducer, and when the measuring range is changed. The device is subsequently zeroed and the system checks that the
settings in the parameter set match the transducer settings.
3.12 Power-saving function (standby)
Menu path: Menu -> Param -> Setting -> Initial setting -> Standby
To save power, the LCD illumination and the GMV2-K power themselves off after set time periods, which can be adjusted.
This function may also be disabled.
Adjustable delay times for switching off the LCD illumination are: 1 min – 1 h. Adjustable delay times for switching off
the device are: 1 min – 3 h.
Note:
• These delay times are reset when measured values are saved or output.
• The standby function is disabled when the output is continuous.
3.13 Cancel serial transmi ssio n
Serial transmission can be canceled with the OFF key.
3.14 Continuous output with a minimum 0.5 second interval peri od
The minimum cycle time has been increased to 0.5 seconds due to the enhanced functionality of the GMV2-K.
3.15 Analog output
The optional analog output is now zeroed with the Zeroadjust key. Additionally, the automatic tracking of zero-point drift
is enabled.
Note:
• The output signal is scaled to ±5V independently of the input signal (passive, active & digital).
• The overload range must be set to 7% (standard).
