2 Safety

The unit has been constructed and tested in accordance with the safety regulations for measuring
and control equipment and has left the plant in perfectly safe condition.
In order to maintain this status and ensure safe operation, observe the instructions and warnings

The Statometer II is intended for the measurements of electric fields on flat surfaces. It provides
fast measurements of electric fields created, for example, through charges on surfaces of plastic,
paper, glass and other materials.

For reasons of safety, unauthorized conversions and modifications of the unit are not permitted.
The installation and operating conditions indicated in these Operating Instructions must be
adhered to.

2.2 Storage of the Statometer II

For storage, remove the rechargeable batteries from the battery compartment underneath. Check
the rechargeable batteries before putting the Statometer II into operation and recharge, if
necessary.

4 Preparing the initial start-up

The unit and its related components may be put into operation, used and maintained only by
persons who have read the operating instructions and follow the instructions, notes and safety
advice.

4.1 Setting up, connecting

1. Before connecting, always check whether the unit is suitable for use with the local mains

voltage. The unit is designed for operation with rechargeable battery, 230 V and 115 V. The
mains voltage is indicated by the number on the fuse holder (Section 3, item 8). To change
the mains voltage, refer to Section 4.2 Mains voltage. The unit will be destroyed if used with
wrong mains voltage.

2. Set up unit at the desired location. Do not place the unit on a surface generating or radiating

heat. Avoid locations exposed to direct sunlight.

3. Ensure that the unit is switched off (off-switch depressed, refer to Section 3, item 1).

4. Ground the unit via the ground connector (Section 3, Pos. 7) using the enclosed grounding

cable.

5. Plug the measuring head connector into the measuring head port (Section 3, item 6) and

screw tight.

6. If required, a recording instrument can be connected to the recorder output (Section 3, item

5).

7. Connect the Statometer II to the mains unless working in battery mode.

8. Put unit into operation.

In case of battery operation, always ensure grounding!

The display will indicate low battery voltage.
Analog = Both polarity LEDs light up
Digital = LO BAT is displayed

Protect measuring head from contamination (e.g. water, oil).

4.2 Setting the mains voltage

On delivery from the factory, the unit is set to a voltage of 230 V.
Check the set mains voltage by reading the number on the fuse holder (refer to Section 3, Para.

2).

Changing the voltage range:

1. Switch off the unit and isolate from the mains.

2. Pull the cable out of the socket for non-heating apparatus at the rear of the unit.

3. Detach the fuse holder in the socket (spring lock) and pull out.

4. Replace the fuse (230 V = 100 mA slow; 115 V = 200 mA slow).

5. Pull out the fuse with the fuse cage from the fuse holder and reattach after turning by 180° .

The new voltage range is now visible on the fuse holder.

6. Reinsert the fuse holder into the socket. Press the fuse holder until the spring lock snaps into

place on both sides.

When setting the mains voltage range, ensure that the correct fuse is
used (refer to Section 7.2).

4.3 Inserting the NiMH batteries

The NiMH batteries are charged when the unit is connected to the mains.

1. Open the cover underneath the unit.

2. Insert the batteries observing the polarity marking.

3. Close the cover.

Observe the polarity when inserting the batteries.

ly use NiMH cells!

5 Application

Preconditions:

The Statometer II and its components must have been connected correctly.
The position of the Statometer II does not affect its functioning.

5.1 Determination of the field intensity

1. Check whether the chassis ground connection has been made. No reliable measurements

can be made unless the unit is grounded via the ground terminal (Section 3, item 7).

2. Pull the protective cap from the measuring head and check for contamination. Clean, if

required (refer to Section 7.1).

3. Keep the measuring head away from electric fields to perform the zero calibration. Press the

range selector button. The impeller in the measuring head now turns, and the unit will
perform an automatic zero calibration.

4. Move the measuring head vertically towards to the measuring surface. The measuring

distance amounts to 30 mm.

5. Read the amount and polarity of the field intensity measured from the display.

6. In case of a capacitor field, the value displayed is not corrected. In case of measurements on

flat surfaces, the displayed value will be corrected by a factor of 1.5.

Example: Measuring value 12 kV/m
Capacitor field 12 kV/m x 1 = 12 kV/m
Surface area 12 kV/m x 1.5 = 19.2 kV/m

Surfaces must be larger than the measuring head diameter (Ø 30 mm).
In case of co
falsified!

In case of very high field intensities and insufficient measuring distance,
a sparkover to the measuring head may occur.

5.2 Determination of potential

The potential (voltage level) of the measured surface area can be determined from the field
intensity measuring value.
The following relationship applies:
Field intensity (in kV/m) x measuring distance (in m) = Potential (in kV)
The measuring distance for the Statometer II is: 30 mm = 0,03 m

Example: Field intensity determined = 12 kV/m

Potential (in kV) = 12 kV/m x 0,03 m = 0.36 kV = 360 V

5.3 Determination of charge density

The surface charge density is proportional to the normal component of the electric field. The
connection is made using the absolute permittivity
The charge density therefore results from the equation
Charge density = field intensity x absolute permittivity
For the

above example:

 = 12 kV/m x 8,86 x 10

-12

As/Vm = 106,32 x 10-9 As/m2

= 8,86 x 10

6 Remedy of defects

In case of malfunction in connection with the Statometer II, first check for correct installation and
fusing (for replacement, refer to Section 7.2). If this does not solve the problem, please return the
Statometer II and the measuring head to HAUG for a check-up.

7 Maintenance and repairs

This unit does not include any parts which can be repaired by the operator.
HAUG only is authorized to repair or calibrate the unit.

Should the unit prove defective or if a defect is suspected, switch off unit immediately and secure
against subsequent reuse.

7.1 Cleaning

The measuring head, and in particular the impeller (refer to Section 3, Fig. 3), must be free of
contamination with water, oil or dust. Clean any contamination from the impeller in the measuring
head using a dry, soft brush. Any deformation or damage to the impeller will result in false
measuring results.

7.2 Changing the fuse

1. Switch off the unit and isolate from the mains.

2. Pull the cable out of the socket for non-heating apparatus at the rear of the unit.

3. Detach the fuse holder in the socket (spring lock) and pull out.

4. Replace the fuse.

5. Reattach the fuse holder.

Use the following fuses only:

Unit type Mains voltage range Fuse

Statometer II 115 V 200 mA slow; 5 x 20 mm
Statometer II 230 V 100 mA slow; 5 x 20 mm

Only use fuses of the type indicated.
