2 Manual TOM 600
1. Product Description
Due to its compact design and battery powered operation the TOM 600 is suited for mobile
applications in industrial areas. Furthermore it can be dri en stationary with the pro ided wall
power supply.
The menu-dri en TOM 600 is operated by only 2 push-buttons and therefore ery user-friendly.
All set measurement parameters are shown in the display for a better orientation. Die pro ided
PC software enables you to perform computer dri en measurements. In addition the
measurement data can be administrated and processed.
The TOM 600 works according to the oltage 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.
While measuring in TIMER=ON mode data, including en ironment parameters, is stored in the
internal EEPROM memory. Thereby the data is maintained and can be read out later ia the
serial PC port.
As resistance alues of some materials depend on air humidity and temperature, these
en ironment parameters are measured and sa ed together with each measurement alue. Thus
reproducible measurements can be performed.

2.1. Initiation
The TERA ohmmeter TOM 600 is shipped with 4 AA batteries and is therefore plug-and-play. For
charging the batteries only the pro ided wall power supply may be used.
For measuring the electrodes ha e to be connected to the appropriate connectors (q. . legend)
and positioned on the object to measure. Afterwards button «B» has to be pressed to power the
de ice on.
Please pay attention mo ing on measurement lines and passing people as they can cause
electrostatic induction at the measurement input.
After powering on the software ersion is displayed::
In case of set measurement time the de ice prompts to press button «B». Afterwards the current
resistance alue and the timer settings are displayed. If the timer is not set, the de ice
immediately returns:
Press button «B» to power the de ice off. In battery mode the de ice powers off automatically
after 5 minutes when no button was pressed.
2.2. Charging the NiMH Battery
The pro ided wall power supply has to be used to charge the batteries or operate the TOM 600.
For this the jack (9) must be connected to the power supply. If the charging works properly the
green indicator LED (8) is lit. The charging time for the pro ided batteries is max. 14h. Longer
charging has to be a oided as batteries can be o ercharged and damaged.
The TOM 600 can be operated up to 12 hours with fully charged batteries.

2. . Range Selection and Measurement Voltage
The TOM 600 pro ides a automatic range selection o er the entire measurement range. The
de ice selects the measurement range according to the connected resistance.
Measurement range Measurement voltage
≤ 200kΩ: 10V DC
> 200kΩ: 100V DC
The automatic range selection can be turned off in the setup. A fixed measurement oltage can
be set. The a ailable options are:
Measurement voltage Measurement range
10V 20kΩ … 200GΩ
100V 200kΩ … 2TΩ
. Setup
By pressing button «A» for about 2 seconds the setup menu is loaded. The de ice displays:
By pressing button «B» (Change) the timer can be switched on and off. If button «A» is pressed
while the display indicates OFF, the timer is turned off. Read on at section 3.1. If button «A» is
pressed while the display indicates ON, the measurement time can be set up next and the de ice
displays:
By pressing button «B» the measurement time is changed as follows:
Press button «A» to confirm the measurement time shown in the display. The de ice returns:
The measurement mode can switched between the a erage o er the whole measurement time
(AVERAGE) or the last alue at the end of the measurement (LAPSE) by pressing button «B».
The displayed mode can be confirmed with button «A».

Pressing button «B» switches between YES and NO. The selected action is confirmed by pressing
button «A». If all data is erased the sa ing will start on File No. 001 the next time. The display
returns:
