• VC 630 and VC 650: measurement of capacitors up to 40 uF max.; VC
670 up to 400 uF
• Frequency measurements up to 4 MHz max.
• VC 630 and VC 650: resistance measurements up to 40 MOhm max.; VC
670 up to 400 MOhm max.
• Continuity test, diode test, transistor test (hfe parameter)
• VC 650 and VC 670: temperature measurements using the temperature
adapter available as an option

Page
• VC 650 and VC 670: signal generator output (TTL) from 1 Hz up to
5 kHz (in steps)
• A measurement must not be performed under unfavourable ambient
conditions. Unfavourable ambient conditions include:
- wetness or excessive air humidity,
- dust and combustible gases, fumes or solvents,
- thunderstorms or storm conditions such as strong electrostatic fields,
etc.
Any use other than as described above can lead to damage to the pro-
duct and can also cause hazards such as for example, short-circuit, fire,
electric shock, etc. No part of the product must be modified or conver-
ted! The safety information must be observed!
2. Introduction, presentation
The three digital multimeters VC 630, VC 650 and VC 670 are menu-dri-
ven instruments each with a multifunction display. The otherwise custo-
mary rotary switch for selecting measurement functions is entirely mis-
sing. Therefore, logically, there are also no contact-closure or other com-
mon switch problems. With the base model VC 630, in addition to the
normal multimeter functions, transistor tests, frequency and capacity
measurement are possible. With the VC 650, in addition temperature
