Frequency indication
Simultaneously to voltage indication, the upper display line indicates the mains frequency in Hz.
With direct voltage „dc“ is indicated.
AC/DC Polarity
Type of voltage is indicated by symbole „~“ for AC and no sign or „–“ for DC. „-“ appears when minus is applied
with dirct voltage to the test electrode with display part. When plus is applied to the test electrode with dis-
play part, no sign appears.
Application in moist environments
The DSP HS11 is approved for indoor and outdoor applications. In case of precipitation, the device has to be
wiped dry before usage. Workings in case of dense fog and impaired visibility are not approved.
5. Energy source
5.1 Check battery condition
The latest battery status is symbolised by a three-stage battery indicator on the display.
indication of battery status
replace the battery soon – few measurements possible
(Battery symbol flashing: no further measurements admissible!)
Attention!
When the empty battery symbol flashes, then no more measurements can be performed and the battery has
to be replaced immediately.
The device requires a 9 V block battery IEC 6LR61 / 6LF22 / 6LP3146 (alkali-manganese).
5.2 Replacing the battery
Loosen the screw at the back of the instrument which secures the battery compartment lid, remove the lid.
Let the battery drop out of the battery compartment with its CAT IV protection cover and exchange it.
Therefore, snap the battery contacts onto the 9 V block battery and insert the battery together with the
CAT IV protection cover into the battery compartment. Put the lid back on the battery compartment and
screw it tight.
Regularly make sure that the battery of your device does not leak. In case it does, you have to replace the elec-
trolyte completely and to insert a new battery.
In case of a long storage period, remove the battery from the device.
Note:
Included in the scope of delivery is one battery. These battery is not to be re-charged. Attempting to recharge it
may cause risk to personal safety and damage to the equipment. The battery may not to be opened. Depleted
batteries must not be disposed with the domestic waste. Please, return batteries at a local retailer or municipal
recycling depot. Return is free of charge and required by law.
6. Change test electrodes
The MultiSafe DSP HS11 can be equipped with
different test electrodes. Those can be easily
screwed onto the high-tension test probes.
After this, perform the function test!
Design of electrodes
The following test electrodes are available
for the MultiSafe DSP HS11:
i = semicircular electrode (standard)
G = peaked electrode with M5-thread
Y = bifurcated electrode
