Safety Instructions

In the case of any damages which are caused due to
failure to observe these operating instructions, the
guarantee will expire. We do not assume liability for
resulting damages.
An exclamation mark inside a triangle points to
important notes in the operating manual. Please
read through the entire manual before putting the
device into operation.
The unauthorised conversion and/or modification of the MS18-2 is
not permitted because of safety and approval reasons (CE).
Never exceed the maximum input quantities.
A reliable display is only ensured at a temperature range of –10°C to
+50°C and a frequency range of 50Hz to 500Hz. The tester is only
authorized for the use in closed and dry rooms.
Avoid all contact to dampness
Never use the tester if there are any visible damages. Before each
use the device needs to be checked if it works correctly.
In commercial and industrial facilities the regulations for the preven-
tion of accidents of laid down by the professional trade association
for electrical equipment and devices need to be observed.
Static electricity e.g., caused by strong rubbing on the plastic hous-
ing, can falsify the reading.
This tester should be kept out of reach of children.
The multitester is not suitable to be used as a screwdriver. Be espe-
cially careful with voltages larger than 25V AC or 35V DC. With volt-
ages like this you can already suffer a life-threatening electric shock.
This tester can only be used in electrical circuits which are protect-
ed with 10A (and/or no capacities larger than 4000VA appear). In the
case of any queries which could not be answered by these operat-
ing instructions, please a consult specialist or contact our customer
service by phone.

Continuity Check 0 – 5 MOhm (direct contact)
Caution!
Lethal danger because of risk of electric shock.
The object to be tested has to be off circuit, electrical
components must be removed. Devices which are
operated with batteries, rechargeable batteries or a
power supply unit, have to be disconnected from the
voltage supply. With 230V alternating voltage devices
the mains plug needs to be pulled. With 230V lines the
main fuse needs to be switched off and must be safe-
guarded to prevent unintentional reclosing. Possibly
built-in capacities have to be discharged.
Touch the battery compartment lid (3) with one
hand and with the other hand the contact of the
component to be tested (e.g., light bulb). Guide
the tip of the multitester to another contact. If
the LED (2) starts to blink, continuity is given
and the light bulb is in working order. The mul-
titester recognises resistances up to 50MOhm.
With this function you can test fuses, resis-
tances, (up to 50Mohm), heating elements,
electrical components such as condensers,
transistors, diodes, coils, etc. simply and easily.
Practice note
- A diode is in working order if the LED starts blinking in conducting
direction (finger on cathode, test tip on anode), the LED remains
dark in reverse direction.
- A NPN transistor is in working order if the LED starts blinking as
soon as the test tip of the emitter or the collector gets touched
while the finger taps the base at the same time.
