The voltage specifications on the DSP-HW 2 are nominal values. The voltage warning
device may only be used in systems up to a maximum of 1000 V AC / 1500 V DC.
The permitted temperature range for use is - 15 ° C to + 55 ° C.
The permissible duty cycle is 2 minutes at 1000 V AC / 1500 V DC.
This means that when there is a voltage signal (red), the ball electrode must be
pulled out of the water after 2 minutes. If the display shows no voltage (green),
the ball electrode can remain in the water indefinitely.
The DSP-HW 2 switches itself off after approx. 20 minutes.
The red LEDs only serve as a warning of dangerous voltages and not as a
measured value.
The response time (change from green to red indication) is less than 1 second.
No special protective equipment for work is prescribed by the manufacturer.
Before use, the housing of the display unit and the earth line including the
clamp must be checked for damage. If damage can be seen, the device must
no longer be used. If the device is very dirty, it must be cleaned before use.
Voltage testers must be checked for function shortly before use.
Check the device using the self-test / function test.
If the display of one or more systems fails, the device may no longer be used.
Only authorized persons are allowed to work with this product.
The user must be familiar with the dangers of voltage measurement and the
observance of the precautionary measures as well as the correct use of the
voltage warning device, see 1.6.
The test of the voltage in the water is only carried out locally.
The test radius around the ball electrode is 1 m and is indicated by the red
limit mark on the test lead. The limit mark must not be sunk in the water in
order to always be able to recognize the test radius.
The voltage is checked 1m around the ball electrode.
Any further work may only be carried out at this measuring point.
Other areas of the water are not tested as a result.
A separate on-site test must be carried out for each area, see 4.2.
The tester has to be stored in a clean and dry environment.
