TERA Ohmmeter TOM-374

The TERA Ohmmeter TOM-374 works with the voltage measuring process. An Electro Field Meter is

integrated as input amplifier with its very high impedance. Through it, it is possible, to measure resistances

directly against earth. High resistances up to 1014 Ohm (100 Tera Ohm) can be measured with a maesure

voltage of only 100 volts and an accuracy of 5%.

Through the built-in microprocessor, a very high comfort is guaranteed.

Charge Plate Monitor CPM-374

The CHARGE PLATE Monitor 374 measures the voltage potential on its integrated Plate-Electrode

according the Fieldmill-Influence-Principal and is suitable to determine the Static Decay Time from a

selected higher voltage threshold to a lower voltage threshold level.

The unit meets the requirements of the European Norm EN 100015 and the American Standard

EOS/ESD S.3.1.

At the upper side of the appliance, there is a plate condenser 150 x 150mm with a capacity of 20pF

±2pF.

This plate will be charged by an internal High Voltage supply with >± 1200 V and then measured the

discharge time in an ionization air. The start and stop voltage can be selected. The pos. and neg.

discharge time as well as the offset voltage will be shown in the display after the end of measurement.

The quality of the area ionization can be decided from it.

Electro field meter

EFM 022 Small hand-held Electro - Fieldmeter with digital display designed to measure electrostatic

voltage potentials (with pre-selected distance) according the fieldmill influence principal.

EFM 120 small very solid Electro - Field meter with high sensitivity to measure the

Electro – DC – Field and electrostatic Charge. The display is a 21 point LED

Bar graph with green Zero – LED in the middle.

EFM 2XX supersensitive Electro - Field Meters for laboratory use, to measure Electrostatic charges

down to < 1V. Appliances in pistol casings with analog - or digital display.

All the Electro - Fieldmeters works with the „Feldmühlen-Influenz-Prinzip“. By the use of a microcomputer,

it will increase the service comfort as well as the operational safety further.

No radioactive substances are used.

1. Description

The TERA Ohmmeter TOM 584 is suitable very well for the mobile use in industrial areas through its

compact housing and the battery power supply. It can also be used stationary with a plug power supply.

The TOM 584 is menu-controlled, has only two keys and is very operator-friendly.

All parameters are shown in the LC - Display.

The included PC-Software is for remote controlled usage, and additionally measuring results can be

administered and processed.

This TOM 584 works with the current - voltage - principle.

Besides the electrode connection sockets, also an additional ground socket exists. The appliance should be

grounded to eliminate parasitic effects (influence effect).

To the transactions of the measurements anuses of tied-up Norm DIN EN 61340 / EOS-ESD 4.1/6.1 can

the measuring time be selected with the internal timer.

With 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.

2. Operating Instruction

2.1. Start operation

The TERA Ohmmeter TOM 584 is delivered with a 9V NiMH – Battery, and is directly ready to start.

Only the enclosed plug power supply should be used for charging the battery, and stationary work.

• The electrodes are connected to the corresponding sockets (s. legend) and placed on the probe.

• The measuring instrument should be grounded.

• During the measurement of very high-ohm-resistors is to be kept that no influence effect is happen on

the measure input.

• To Switch On the unit press key „B“.

After switching on, first the software version is shown. Provided the timer is „ON“, in the display appear

press start. You can start the measure by pressing key „A”

The current resistance value and the timer attitude are shown afterwards.

If the timer should be turned off, immediately appears in the display:

>2.0xE12Ω

ΩΩ

ΩT=OFF

• To switch off the appliance press again key „B”.

• In the battery mode the unit switches off, if no button was pressed, automatically after approximately

5 minutes.

2.2 Charging the 9V Battery

The TOM 584-TF is allowed to operate only direct with the enclosed power supply. Also only with this the

installed NiMH – battery should be loaded. Connect the power supply to the integrated socket, and but the

plug power supply to a power socket. The NiMH - battery is completely charged after maximum 14 hours

and supplies the TOM 584 approximately 2 hours in the continuous operation.

2.3. Measure ranges and measure voltages

The TOM 584 has an automatic ranging approve the hole resistor range. The appliance, accordingly the

adjacent resistance, selects the Measure voltage automatically.

• Measured resistor less then 200 kΩ—- Measure Voltage 10 VDC

• Measured resistor higher then 200 kΩ—- Measure Voltage 100 VDC

3. „set-up“ Function

Through simultaneous pressing the two keys „A” and „B” the „set-up" function is called.

In the display appears shortly:

SET TIMER !

After that it appears: ↓

↓↓

↓ON TIMER OFF↓

↓↓

↓

By pressing key „B“, the timer is switched off and the unit makes a reset.

By pressing key „A“, the timer is switched on and the countdown - time can be selected between1 and 240

seconds. In the display appears:

↓

↓↓

↓OK T=001s STEP↓

↓↓

↓

By pressing key „B“, it appears T= 002s and than in 1 second Steps up to10 second.

After that the timer starts with T=010s - T=015s - T=020s the changing steps are now 10 Seconds up to 60

Seconds, after this you get 60 second steps up to 240 seconds.

By pressing the „A“ key you choice the timer time and in the display appears:

↓

↓↓

↓AVERAGE LAPSE↓

↓↓

↓

By pressing key „A“, the middle value over the measure time will be displayed (AVERAGE).

By pressing key „B“, the last value after the end of the measure time will be displayed (LAPSE).

Now, it is asked whether they should be deleted in the EEPROM stored data (file). In the display, it appears:

↓

↓↓

↓Y DEL FILES NO↓

↓↓

↓

By pressing key „B", no files will be deleted, and the next files are saved with File No x+1, than the unit

makes a reset.

By pressing key „A“, all saved files will be deleted, and the next file to save in the EEPROM starts with File

No. 001. In the display appears for approximately 2 seconds:

WAIT . . .

After that appears FILES DELETED !

Now the Unit makes an Reset and after that in the display appears:

↓

↓↓

↓START T=xxxs

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

After 5 second it 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 then later can be read out over the

PC - Interface.

3.1 Timer

If the timer was not activated, the TOM 584 directly switches on the resistance display in the on-line

operation. In the display appears:

=5.5xE10Ω

ΩΩ

ΩT=OFF

4. Other Display Information’s

If the maximum measurement is exceeded appears in the display:

>2.0xE12 (T=OFF)

If the minimal measurement becomes under-stride appears in the display:

<2.0xE04Ω

ΩΩ

ΩT=OFF

If the Battery Voltage is lower than 7,6 Volt, report the unit in the change with the current line:

LOW BATTERY !

The accumulator must be charged again, however the current measurement can quietly be completed. If the

Battery Voltage is lower as 7,0 volts, following display appear one after the other. Then the unit

automatically switches off, to avoid a destroying of low Voltage of the battery.

LOW BATTERY

AUTO OFF

SWITCHING OFF

4.1 Display contrast

On the right side of height of the display there is a hole trough it you can screw a potentiometer for adjust

Contrast of the LCD - Display.

To select the Menüpunkte use Coursor - Buttons ↑↓. With the <Enter> Button Menüpunkt will be started.

→Change start condition

Timer ? (0-240s) give in direct the time for the count-down (0 – 240 sec).

Average ? [y/n] with “y” the mid-value (Average) of all the measurements, during

the count-down timer is running, are calculated.

with „n” the last measured value is shown in the display (Lapse).

Important ! The changed items are not stored in the EEPROM !

→Start Measurement

With <Enter> the count-down timer for the measurement cycle will be started. After the count-down

timer returned to zero it is possible to store the complete measurement-curve.

(100ms – sample-time).

Save Data ? [y/n] with “y” the measured values will be stored in the file MV.DAT .
