Avoid an operation near:
- strong magnetic or electromagnetic fields
- transmitter aerials or HF generators,
since this could affect the measurement.
If you have a reason to believe that the device can no longer be operated safely, disconnect it immedi-
ately and secure it against being operated unintentionally. It can be assumed that safe operation is no
longer possible if:
- the device is visibly damaged,
- the device does not operate any longer and
- the device was stored under unfavourable conditions for a long period of time or
- it has been subjected to considerable stress in transit.
Do not switch the measuring instrument on immediately after it has been taken from a cold to a warm
environment. The condensation that forms might destroy your device. Leave the device switched off and
wait until it has reached room temperature.
Do not leave the packaging material lying around carelessly since such materials can become danger-
ous toys in the hands of children.
You should also heed the safety instructions in each chapter of these instructions.
Product description
The multimeter (referred to as DMM in the following) indicates measured values on the digital display.
The measuring value display of the DMM spans 2000 counts with VC130 and VC150 as well as 4000
counts with VC170 (count = smallest display value). The VC170 sets the right measuring range auto-
matically (AUTO range). However, manual selection of the measuring range is still possible.
The measuring device can be used for do-it-yourself or for professional applications (up to CAT III 250V).
For better readability, the DMM can also be mounted with the clip on the rear.
Rotary switch (4)
The individual measuring functions are selected via a rotary switch. With the VC130 and the VC150, the
measuring range is selected manual, with the VC170 automatically (auto range; the right measuring
range is always set here automatically).
Turning the measuring device on and off
The DMM VC130 and VC150 are turned on and off via the button "POWER". When the rotary switch is
set to "OFF", the VC170 is turned off. Always turn the measuring device off when it is not in use.
Prior to working with the measuring device, you first have to insert the enclosed batteries.
Insert the battery as described in the chapter "Cleaning and Maintenance". A 9V block battery is required
for voltage supply. This is part of the delivery.
