4.5 Test water and setup pump
Only touch the DSP-HW 2 by the handle of the display unit and in the hand area of the handle cable.
Lower the handle with the ball electrode into the water.
Place the display outside of the water so that the LEDs are clearly visible.
Note!
The red limiting mark indicates the maximum test radius. Do not sink this into the water in order to
identify the test radius. It must be checked at the place where a pump is to be used.
Do not touch water!
Leave the danger area
immediately!
Do not use a pump!
Immediately stop all work in
the danger area.
Do not touch water!
Check the ground connection
of the DSP-HW 2!
Do not enter the water!
Insert the pump at this
point while observing the
green LEDs
.
Water currently has earth
potential and no voltage.
Note the limit mark (red).
The limiting mark indicates the maximum
tested safety area!
The limiting mark (red) must not be sunk
into the water!

Note:
The DSP-HW 2 switches off automatically after 20 minutes. If you want to check further:
Leave the ball electrode in the water, press the button, if there is voltage this is displayed directly or if the potential is 0 V, the
self-test shows „Rdy“ and the display jumps to 000 V. If the message „Test“ remains, the grounding must be checked.
Operational readiness to check!
Voltage present!
No voltage
