HAUG Static Meter Ι
Please retain for future reference.
Type:HAUG Static Meter Ι12.7210.000
1Proper use
The unit is not approved for use inside explosive areas.
The use in power plants is not allowed.
This unit cannot measure alternating fields > 1 Hz.
The electrofieldmeter must be grounded at the presence of high electrostatic
charges.
The first measurement must be conducted at sufficient distance from the
object to evaluate the voltage potential safely.
Sparking on the modular system can cause damage to the unit and must be
absolutely avoided.

2.1 Basic information about electrostatics
Electrostatic discharge (ESD) causes problems at many electronic working
places, especially where sensitive micro-electronics (IC and MOSFET) are
handled.
Other industrial areas are also concerned such as telecommunication, plastic
converting and explosive areas. ESD can slow down processing speed in
manufacturing and is therefore a significant cost problem. Static electricity is
generated by personnel, their clothing, handled materials and equipment and
can exceed 10.000 volts. Static sensitive electronic devices could be
damaged at static voltage levels less than 100 volts. Static voltage exceeding
3.000 V can cause sparking, which is a danger in explosive areas.
2.2 Short description
Small hand-held electrofieldmeter with digital display designed to measure
electrostatlc voltage potentials (over pre-selected distance) according the
fieldmill influence prlnclple.
2.3 Description
The electrofieldmeter HAUG Static Meter Ιis designed to measure
electrostatic voltage potentials over the pre-selected distance (distance
between sensor head and object). The selection of the distance is menu-
driven and the following distances are available: 1 cm, 2 cm, 5 cm, 10 cm and
20 cm. The internal micro-computer considers automatically the measured
field strength (V/m) and the pre-selected distance (cm) to calculate the
voltage potential (volt) accordingly. For voltage levels exceeding 1000 V, the
digital display will show the values in kV for a better illustration.

2.4 Measurement principle
The electrofieldmeter is a parametric operating amplifier. The influenced
charges, caused by the electrical field, generate an alternating current
proportional to the electrical field strength. The selective operating amplifier
measures the current without taking energy over the averaged time.
There are no radioactive components used inside the unit.
2.5 Calculating the electrical field strength
In order to compare to field strength measuring instruments, the shown
tension can be converted into the equivalent field strength. To do this, the
shown value has to be divided by the actual measuring distance (in meter).
Example:
Shown value:2 kV
Actual measuring distance:2 cm = 0,02 m
Calculated electrical field strength:E = 2 kV/0,02 m = 100 kV/m

Operation

HAUG Static Meter Ι
3Operation
Press the "function/on"-key to switch the unit on. Press the "function/on"-key
twice in short intervals to switch the unit off.
The unit will switch off automatically when the "function/on"-key was not used
for 5 minutes.
3.1 Hold
The unit has a hold-function keeping the measured value stored on the
display . Press the "function/on"-key once shortly to activate the hold function
-"hold" will appear then in the first row of the display, while the stored value is
shown in the second row. To exit the hold-function, press the "function/on"-
key once again shortly and the actual measurement value will appear on the
display.
3.2 Measurement ranges
The measurement distance of 2 cm is always indicated after each switch-on.
If this distance is used, the unit has to be positioned at the distance of 2 cm
monitoring the object. This distance is ideal in most cases, as voltage levels
up to 20 kV can be measured (please see Technical Data).
The measurement distance should be increased, if the measurement object is
highly charged or when the object has a rough surface. The lowest
measurement distance of 1 cm should be selected, where low charges are
present and the surface of the object has a smooth surface.

3.3 Change measurement distance
Press and hold the "function/on"-key (approximately 2 s) until "change
distance" will appear in the second row. The pre-selected distance in cm will
be displayed in the first row. Press the "function/on"-key once shortly to
change the measurement distance. With each short press of the
"function/on"-key the proposed distance will appear as follows:
2 cm è5 cm è10 cm è20 cm è1 cm è2 cm (and so on).
When you reach the right distance, please wait (do not press the
"function/on"-key) until the actual measurement value appears in the second
row. The new selected distance is now also shown in the first row. Please
consider this selected distance for the following measurements. The distance
will be measured from the electrode positioned 3 mm apart from the housing
on the modulator side. It is necessary to add 3 mm to any selected distance
starting from the housing of the unit.
Please note:
The measurement distance will change back to 2 cm after each switch off and
on of the unit!
3.4 Distance support
With any equipment you will get 2 distance supports with a length of 26 mm.
The distance supports can be screwed into the aluminium plate on the
modulator side, which will always provide the right measurement distance for
the standard setting of distance = 2 cm.
3.5 Display
The alphanumeric Liquid Crystal Display (LCD) consists of 2 rows for 12 digits
each. The measurement distance in cm will be shown in the first row, while
the voltage reading in volts is displayed in the second row.
When the level of 999 volts is reached, the display will switch automatically
into the kV-mode. The display of the voltage reading appears always in 3
digits, such as: 578 V; 3.85 kV; 24.0 kV and 274 kV respectively.
Select a greater distance if "overflow !" appears on screen!

3.6 Battery control
The measuring unit has a permanent battery voltage control. If the battery
voltage is less than 7.5 volts then "Low Battery" appears in the first row of the
LCD and the 9 V battery has to be replaced or the accumulator has to be
charged with the supplied battery charger!
If the battery voltage will become less than 7.0 volts, then "auto off" will
appear for approximately 2 s in the second row and unit will switch off to
avoid a total discharge and acid leakage.
Note: Please use Alkaline or Lithium 9 V blockbatteries only or rechargeable
NiCd or NiMH accumulators!
If rechargeable batteries are preferred, please use a suitable battery-charger
for recharging separately the batteries. Please note the manufacturer's
advises !
3.7 Grounding
The unit has to be connected to ground for correct measurements of voltage
levels and polarity. Use the grounding socket (4) of the unit for the connection
to earth potential. The unit consists of a conductive housing, thus allow the
use without grounding cable if the operator is on earth potential (e.g. wears
conductive shoes, uses a wrist strap or touches grounded parts with one
hand).
3.8 Zero Adjustment
A zero adjustment is normally not necessary. In case, that the unit does not
indicate U = 000 V while the modulator system is shielded (e.g. grounded
person covers the modulator system with one hand), use the trimmer (6) for
zero adjustment. The last digit can be ignored as the caused measurement
failure is much lower than the specified tolerance.

HAUG Static Meter Ι
4Maintenace and Repair
Except the battery the instrument does not contain any parts which require
maintenance or repair by the user. Any repairs or adjustments neccessary
may only be carried out by HAUG GmbH &Co. KG. If a unit is faulty, take it
out of operation and send it to HAUG GmbH &Co. KG.
It is very important not to touch parts of the modulator system. The parts must
be free of foreign materials, such as dust, any spray or similar particles as
well as condensed water. If needed, the modulator system could be cleaned
with alcohol and a dust-free tissue, when switched off. Please avoid any
deformation of rotor!
4.1 Replacement of battery
The 9 V blockbattery has to be replaced when "Low Battery" appears on
screen. Please switch the unit off before opening the battery compartment.
Take out the battery and remove the connector clip. Put the connector clip on
the new battery and put it into the compartment. Close the compartment.
