3 Product Description
1. Product Description
Due to its compact design and battery powered operation the TOM 610 is suited for mobile
applications in industrial areas. It also can be operated stationary with the provided wall power
supply. The menu-driven TOM 610 is operated by only 2 pushbuttons and its touch display and
therefore very user-friendly. All set measurement parameters are shown in the display for a
better orientation. The provided PC software enables the user to perform computer driven
measurements.
The enclosed PC software also allows the TOM 610 to be operated computer-controlled.
In addition the measurement data can be administrated and processed.
The TOM 610 works according to the voltage current measurement principle. The measurement
time required by norms, like DIN EN 61340 or EOS-ESD 4.1/6.1, can be set with an internal
timer.
As a new world innovation, we measure the „Break-Down“ Resistor and Voltage and also the
„Break-OFF“ – Time if it happens.
The measured data including environment parameters, can be stored in an internal memory (up
to 200 records). Thereby the measurements are maintained and can be read out later via the
USB interface.
As resistance values of some materials depend on air humidity and temperature, these
environmental parameters are measured and saved together with each measurement value.
Thus, reproducible measurements can be performed.

As long as the selected measuring voltage is not stable, the displayed measured value is
highlighted in blue. If the measuring range is exceeded “Overflow” and if it fell below the range
“R < xxxOhm” will be displayed. (depending of measure voltage)
When the measured value is displayed without a blue background it is stable !
This can take up to a few seconds with very high resistances.
As a rule, we recommend a max. Measuring voltage of 100V !
Use 500V or 1.000V only if problems occur by 100V !
IMPORTANT !! Umess > 100V => Do not touch the electrodes during the measurement !
After switching on it can also take a few seconds until the temperature and humidity are
displayed. As long as these are set to zero no operation is possible !

optimal contact resistance (see cleaning the electrode)
 The covering to measure should also be cleaned
 Measurements may only be performed in zero-potential conditions
 The measurement line should be as short as possible but as long as necessary
 For the measurement of high resistances teflonized measurement lines are inevitable
 For repetitious accuracy in high resistance ranges holding time or a timer function
should be considered
 To avoid influences of electrostatic induction cables must not be moved during the
measurement
 The conductivity of some materials depends on temperature and humidity, therefore
these values need to be logged
 For adequate accuracy the corresponding norms should be complied with the standards
Cleaning the Electrode
