GSV-2MSD-DI Strain gage Data Logger
Connection and commissioning
To switch on, press the MODE button until the display is illuminated.
The device contains a battery that is charged by connecting the power adapter supplied.
The “ON” LED flashes while charging.
To switch off, hold the MODE button (outside the menu) down and confirm the following
message “Power off? (OK)“ by pressing the OK button.
Please use SDHC Memory Cards, class 6 or class 10, but no UHS 2.
Operating the menu
The device has two main menus:
Logger menu.
The logger menu has the following functions:
•View and set data recording mode on the SD memory card,
•Select USB connection mode,
•Select display illumination characteristics,
•Display battery life,
•Set date and time,
•Select additional functions e.g. display and recording of maximum, minimum and average
measured values.
The Logger menu can be reached by pressing the MODE button from the measured value
display or via the last entry of the measuring amplifier main menu.

card as long as the OK button (at measured value
displayed) is pressed
➔Set Log: OFF No Recording

➔USBmode: SDcard The device is a Mass Storage
Device when connected to the USB port, which provides
access to the data on the SD card. Simultaneous
recording of measured value to file is not possible. If
this mode is activated, recording is switched off.
➔USBmode: Comm The device is in serial USB mode.
Our communication programs (e.g. GSVcontrol,
GSVmulti) can then be used. A standard driver is loaded
when connected for the first time, see below
➔USBmode: none USB is switched off.

➔USB power: ON, OFF
If power supply is via USB port is enabled, the GSV-

connected to a PC and configured as an USB device. If
the device is switched off, the battery can be charged.

•If a setting is in brackets in Level 1, this means that this setting has been selected
but is not currently active. This is the case if the conditions for this operating mode
are not met. Example:
•Logging (on): SD card is not inserted or write-protected or full or defective.
•USBmode: (SDcard): USB cable is not connected or no SD card is inserted
Measuring amplifier menu
The measuring amplifier menu is used to set the parameters of the measuring amplifier, for
example:
•Sensor scaling factor
•Unit
•User-definable offset
•Parameter memory
The measuring amplifier main menu can be reached by pressing the MENU button from the
measured value display.

entry.
For numeric settings: to move the cursor left.
UP To move around the menu within the same level: switching to the next entry.
For measured value mode=MaxMin: to switch from one measured value display to
the next one up.
For numeric settings: to increase number and/or setting above the cursor.
DOWN To move around the menu within the same level: switching to the previous entry.
For measured value mode=MaxMin: To switch from one measured value display to
the next one down.
For numeric settings: to decrease number and/or setting above the cursor.
OK
(RIGHT)
To confirm the entry or move down one level.
For measured value display and recording mode “withOK”: to record measured values
to file.
For numeric settings: to move the cursor right.
SHORT To connect the +Ud and -Ud inputs (short-circuit of sensor signal)
ZERO To trigger an automatic zero adjustment.
umber setting
To set a numerical value and the date or time, move the cursor right by pressing OK and left
by pressing MENU. The digit (and/or the month) above the cursor flashes and can be
increased or decreased using the UP / DOWN buttons.
For the setting to take effect, the OK button must be held down until the whole number
