1. Application
The MultiSafe DSP HS11 is a two-pole voltage tester for alternating voltages up to 11 kV AC and direct voltages up to
16 kV. It is particularly suitable to detect voltage quickly and securely at capacitor banks and links of converters.
The DSP HS11 is approved for indoor and outdoor applications.
Voltage is signalised by one LED and the value is indicated digital on the LCD. With the self-test the functions of the
testing device can be checked easily and quickly. Stand-by and abscence of voltage are signalised by a green LED.
1.1 Intended use
This device is intended for use in applications as described in the operating instructions only.
Thus, it is imperative to observe the notes on safety and the technical data in conjunction with the ambient
conditions. Any other form of usage is not permitted and can lead to accidents or destruction of the unit.
Any misuse will result in the expiry of all guarantee and warrantly claims.
2. Safety Precautions
In order to maintain flawless technical safety conditions, and to assure safe use, it is imperative that you read
these operating instructions thoroughly and carefully before placing your instrument into service, and that you
follow all instructions contained therein otherwise there is danger of life!
Please observe the following safety precautions:
The voltages indicated on the MultiSafe DSP HS11 are rated voltages. The voltage tester may only be
used in systems working within this rated voltage range.
Faultless indication of display values is only guaranteed between -15°C ... +55°C.
Hold the instrument only beneath its hexagonal limiting dics, do not touch test probes and test electrodes.
The test probes may only be connected up to the red limiting mark to live or grounded plant components.
With all other parts of the voltage tester the distance has to be kept as big as possible.
The maximum on-time of the DSP HS11 is 15 minutes.
Only qualified persons may carry out work with these device. The user needs to be farmiliar with the risks
for measuring voltage and compliance with safety regulations and the proper use of the voltage detector.
Workings may only be performed with appropriate personal protective equipment. Observe the minimum
object distance to other plant components that are energized or earthed and use personal protective
equipment as specified by national accident prevention regulations
(in Germany: BGV A3 or EN 50110-1).
Just before they are used, and as possible afterwards as well, voltage testers need to be checked to ensure
they function correctly. Check the instrument at a known voltage source by performing the self-test /
function test. If the display of one or several systems fails in the course of checking, the instrument must
not be used again.
The red LED
only serves as a indication for hazardous voltage and not as measurement
value.
This voltage detector may not permit to clearly indicate the absence of operating voltage in case of
interference voltage because of its relatively high internal impedance. When the indication “voltage
present” appears on a part that is expected to be disconnected of the installation, it is recommended
confirming by an other means that there is no operating voltage on the part to be tested.
Before use, the battery compartment must be closed.
The voltage tester may only be dismantled by authorized personnel.
Before using the device check the housing and connecting line for visible damage. If damages are visible the
voltage tester may not be placed into operation. In case of strong dirt contamination, the tester must be
cleaned before use.
The tester has to be stored in a clean and dry environment.
