TERA Ohmmeter 600
SYSTEM PROF. DR. ING. HANS KLEINWÄCHTER
The TERA Ohmmeter TOM 600 operates with the Voltage-Current-Measurement.
High resistances up to 2x1012Ohm (2 TERA Ohm) can be measured with a voltage of
100 volts and a precision of 5%
As peculiarity, the ambient temperature and the humidity will be measured and stored to
every measured resistance value

Description
2. Operating Instruction
The TERA Ohmmeter TOM-600 is suitable very well for the mobile use in industrial areas through its
compact housing and through the battery power. It can also be used stationary with a plug power supply.
Important: Don’t use the AC-Adapter without installed rechargeable batteries.
The TOM-600 is menu-controlled, has only two buttons and so it is very operator-friendly.
All parameters are shown at the LC - Display.
The included PC-Software is for remote controlled usage, and additionally measuring results can be
administered and processed.
The TOM-600 works with the voltage – current measure - principle.
To the transactions of the measurements anuses of tied-up Norm DIN EN 61340 / EOS-ESD 4.1/6.1 the
measuring time can be selected with the internal timer.
At Timer = ON the measurement values inclusive the air parameters can be stored in the internal EEPROM.
They don’t are deleted by switching off the unit. The values can be read out trough the PC-Interface at all
times.
Since the resistance values depend very strongly on the Humidity and the air temperature,
these influences are measured together with the resistance value.
So a reproducible measure ment is given.
2.1 Start Operation
The TERA Ohmmeter TOM 600 is delivered with 4 x Mignon (AA) NiMH – Batteries, and is directly ready
to start. For charging the batteries and stationary operation use the enclosed plug power supply only.
l The electrodes are connected to the corresponding sockets (s. legend) and place on the probe .
l During the measurement of very high-ohm-resistors is to be kept that no influence effect is happen on
the measure input.
l To Switch On the unit press key „B“ ON/OFF.
After switching on, first the software version is shown.
Provided the timer is „ON“, in the display appears press start. You can start the measure by pressing key
“A” start. The current resistance value and the timer attitude are shown afterwards.

If the timer should be turned off, immediately appears at the display:
>2.0xE12W T=OFF
* mathematical representation of technical representation < 2TW
* * Alternating to the timer display T=OFF is shown the measure voltage mode: Auto, 100V or 10V
To turn off the appliance press again key B .
In the battery mode the unit turns off , if no button was pressed, automatically after approximately 5 minutes.
2.2 Charging the NiMH Battery
The TOM 600 allowed only to operating directly with the enclosed power supply. Also only with these the
installed NiMH – batteries can be charged. Connect the power supply to the integrated socket, and connect
the plug power supply to a power socket. If the appliance is switched off, and the charging work correct, the
green Charge LED shines.
The NiMH - batteries are completly charged after maximum of 14 hours and good for > 10 hours
continuous operation. A longer charging time can dammage the batteries.
2.3 Measure Range and Measure Voltage
The TOM 600 has an automatic ranging approve the whole resistor range. The appliance, accordingly the
measure resistance, selects the Measure voltage automatically.
l Measured resistance less then 200 kW —- Measure Voltage 10 VDC
l Measured resistance more then 200 kW —- Measure Voltage 100 VDC
In the Set-Up this automation can be switched off, and a constant measure voltage can be select.
The measure ranges are than as following :
l Measure voltage 10V -- measure range 20kW .... 200GW
l Measure voltage 100V -- measure range 100kW .... 2TW

UP Function
By pressing the key (A) Set-Up longer as 2 seconds the „set-up" function is starting.
At the display appears:
By pressing key (B) „Change” the timer is switches between off and on.
If pressing key (A) „Set-Up“, by TIMER OFF the timer is switched off and you can continued by point 3.1.
If you press the key by TIMER ON, you can now choose the measure time.
In the display appears :
By pressing key (B) „Change“ it appears T= 002s and than in 1 second Steps up to10 Second.
After that the timer starts with T=010s the changing steps are now 10 Seconds up to 60 Seconds, after this
you get 60 second steps up to 240 seconds.
Press the (A) „Set-Up“ key to choose the displayed timer time.
At the display appears:
By pressing key (B) „Change” the timer is switching between AVERAGE and LAPSE.
Press the (A) „Set-Up“ key to choose the displayed timer mode.
Now, it is asked whether you will delete the EEPROM stored data files.
In the display appears:
By pressing key (B) „Change” the display is switching between YES and NO.
By pressing the (A) „Set-Up“ key if YES is displayed, all files in the EEPROM memory will be erased.
By pressing the (A) „Set-Up“ key if NO is displayed, no file will be erased, and the next file is storage by the
next free file number.
In the 1st line at the display appears for approximately 2 seconds:
After that it appears in the 2nd line:
SET TIMER !

3.1 Measure Voltage/Display Mode
Now it will be ask for your choose off the measure voltage.
In the display appears :
VOLTGE MODE :
AUTO (MAN.10V) (MAN. 100V)
By pressing key (B) „Change” the display is switching between AUTO (Automatic), MAN. 10V, and MAN.
100V. Press the (A) „Set-Up“ key to choose the displayed voltage mode.
After that, it will be ask for your choose off the display voltage.
DISPLAY MODE :
R>2.0xE12? (R>2.0 T? )
By pressing key (B) „Change” the display is switching between the mathematical and technical displa y form.
Press the (A) „Set-Up“ key to choose the displayed display time.
Now the unit will execute a reset, and in the display appears if timer is on, else go to point 3.2 Timer off.
T=xxxs Avg Auto (Lap) (+10V, +100V)
PRESS START !
By pressing key (A) „Start” the next measurement will be started.
The timer decrements in 1 second steps up to Zero, then the measure value will appears in the display as
Ravg by AVERAGE - Mode and Rlap by Lapse – Mode.
In the 2nd line the air temperature and the humidity is displayed:
Ravg = 2.5xE9? (Rlab = 2.5 G? )
AIR: xx°C xx%r.F
Alternates all 2 second in the 2nd line appears:
FN:xxx T=xxxs
By pressing key (A) „Start“ the measure value together with the air temperature and the Humidity will be
saved in the EEPROM using the displayed File – No. These values can be read later with the PC - software.
3.2 Timer
If the timer is not activated, the TOM 600 directly switches on the resistance display in the on-line operation.
According to the chosen display mode and voltage mode in the display appears:
Example:
R=5.5xE10W T=OFF AUTO
AIR: xx°C xx%r.F

If the maximum measurement is exceeded appears at the display:
Measure voltage = Auto, 100V R>2.0xE12? (R>2,0 T? )
Measure voltage = 10V R>2.0xE11? (R>200 G? )
If the minimal measurement is under-stride appears at the display:
Measure voltage = Auto, 10V R<2.0xE04? (R<20 k? )
Measure voltage = 100V R<1.0xE05? (R<100 k? )
By searching the measure range, it appears in the 1st line of the display :
