Self and personnel protection

■

Electric shock may result in major injuries or 

death and may endanger the functionality of 

objects (e.g. damage to the device). 

■

The proper function of the voltage tester must 

be checked shortly before use.

■

Ensure that measuring leads and the device are 

in proper working order.

■

Check the device by connecting it to a known 

power source, e.g. a 230 V socket.

•  If the display for one or more functions fails 

in the process, the device must no longer 

be used and must be checked by qualified 

specialist personnel.

■

Hold the device only at the handles, avoid 

touching the test probes!

■

Read and comply with the five safety rules

1. 

Disconnect mains

2.  Prevent reconnection

3. 

Test  absence  of  voltage  by  approved  means 

(establish  absence  of  voltage  using  two-pole 

voltage indicators)

4. 

Ground and short-circuit

5. 

Protect adjacent live parts using covers or screw 

off

Safety in the workplace

■

Avoid operating the device in the vicinity of 

electric welding machines, induction heaters 

and other electromagnetic fields.

■

After abrupt changes in temperature, the 

device must be allowed to adapt to the new 

ambient temperature for approx. 30 minutes to 

stabilise the IR sensor.

■

Do not expose the device to high temperatures 

for any length of time.

■

Avoid dusty and humid ambient conditions.

■

In commercial facilities the accident prevention 

regulations (in Germany issued by the commer

-

cial trade association for the safety of electrical 

systems and equipment) must be observed.

General safety instructions

■

Always visually check the device for damage 

before initial use and after transport. Ensure 

any damage is repaired by trained service 

personnel prior to initial use.

■

The device must not be operated in damp 

conditions.

■

Do not use with the battery compartment open!

■

The measuring leads must be disconnected 

from the measuring circuit during battery 

replacement.

■

In order to protect the device from damage, 

remove the batteries if the device is not in use 

for a prolonged period of time.

■

Measurement devices and accessories are not 

toys and should always be kept away from 

children!

■

Only use the enclosed safety measuring leads 

or equivalent measuring leads that comply with 

the correct measuring category CAT IV 600 V.

■

To avoid electric shocks, precautionary 

measures must be observed when working 

with voltages greater than 120 V (60 V) DC 

or 50 V (25 V) eff. AC. According to DIN 

VDE standards, these values represent the 

limit at which exposed touchable surfaces 

are still safe. (Values in brackets apply for, for 

example, medical or agricultural applications)

■

The testing device must only be used in the 

specified measuring ranges.

■

Use only genuine Würth accessories 

and spare parts.
