Proper Use; Controls (Fold-Out Page) - VOLTCRAFT CC-421 Notice D'emploi

Proper use

- Operates as DC source up to 19.99 mA max. at 500 ohm or 24
mA max. at 400 ohm.
- Measuring DC currents up to 24 mA max.
- Measuring 2-conductor loop currents up to 24 mA max. at a loop
voltage of 12 VDC (±2VDC) from the current calibrator.
- Performing measurements under unfavourable ambient conditi-
ons is not permissible. Unfavourable ambient conditions are:
- Moisture or excessive air humidity
- Dust and combustible gases, fumes or solvents
- Thunderstorms or similar conditions such as strong electrostatic
fields etc.
A use other than the one described above is not permissible and
causes damages to the measuring device(s). Furthermore, it invol-
ves hazards such as short-circuit, fire, electric shock, etc.! The enti-
re product must not be changed or modified! The safety instructions
must be adhered to!
Controls
Illustration (fold-out page)
1. LC-display (liquid crystal display), 3 1/2-digit up to 199.9 max.
2. Sliding switch for adjusting the functions mA-MEASURE (mA cur-
rent measurement)– Power/mA-MEASURE (mA-loop current
measurement) – CURRENT SOURCE – VOLTAGE SOURCE
3. Sliding switch "POWER" for "O" (= device off) and "I" (= device on)
4. Sliding switch for adjusting the current range and thus the (digit-)
resolution
5. Adjusting knob (helipot) for adjusting the output current at the
current source or the output voltage at the voltage source.
