1.2.2 Safety rules when installing and hand-

ling

Observe the following rules when set-

ting up the appliance:

1. Do not operate it in extremely cold or hot

locations, in a vehicle in summertime or in the

vicinity of a fan heater.

2. Never switch on the appliance immediately

after it has been moved from a cold into a

warm room. The condensation created may

destroy your appliance. Leave the appliance

switched off until it has reached ambient

temperature.

3. Avoid the following unsuitable environmen-

tal conditions:

- Dampness or excessively high atmospheric

humidity

- Dust and ﬂammable gases, vapours or sol-

vents

- Severe vibration

- Strong magnetic ﬁelds such as those in the

vicinity of machinery or loudspeakers.

4. Never block the ventilation slots or openings

in the housing because this can cause heat

accumulation and/or damage.

5. Never operate the appliance near hot sol-

dering bits.

6. Never lay the oscilloscope with its controls

side facing down because this can damage

the adjusting knobs.

1.2.3 General safety instructions

1. Oscilloscopes OS-3020 D and OS-3060 D were

manufactured and tested in accordance with

DIN 57411 Part 1/VDE 0411 Part 1, Protective

measures for electronic equipment, and left

our factory in a perfectly safe condition.

To keep them in this condition and to ensure

their safe operation, the user must observe

the safety instructions and warnings con-

tained in these operating instructions.

2. The appliance is a Class I instrument. It is

equipped with a VDE tested power cord with

a protective conductor and must therefore

only be connected to and powered by a 230 V

AC mains supply with protective earthing.

3. Make sure that there is no break in the

(yellow/green) protective conductor in the

power cord, in the appliance or in the mains

supply because this would create a risk of fatal

injury.

4. Measuring appliances must be kept away

from children!

5. On commercial premises, the accident preven-

tion regulations of the Association of

Industrial Professional Associations with re-

spect to electrical systems and operating

equipment must be observed.

6. In schools, training centres and DIY work-

shops, the operation of measuring appliances

must be supervised by responsible, trained

personnel.

7. Opening covers or removing parts can lead to

live parts being exposed, unless this can be

performed manually. Connection points can

also be live. Before being balanced, serviced

or repaired or having any parts or com-

ponentry replaced, if the appliance must be

opened, it must ﬁrst be isolated from any

sources of voltage or voltage circuits. If, sub-

sequently, it is absolutely necessary to balance,

service or repair the open appliance while

live, this must be carried out by a qualiﬁed

technician familiar with the risks involved and

the relevant regulations (VDE 0100).

8. Capacitors inside the appliance may still be

charged even after the appliance has been

isolated from all sources of voltage and voltage

circuits.

9. Make sure that only fuses of the speciﬁed

type and speciﬁed current rating are used as a

replacement. The use of rewired fuses or

shorting out the fuse holder is not per-

missible.
