To keep your installation safe, measure your earth connection! yy 2P resistance/3P earth resistance measurement up to 50 kΩ for highly resistive terrain yy Automatic stabilization of the measurement yy Help with placing the stakes – average and 52%/62%/72% deviation yy Leakage current measurement from 0.5 mA yy Battery recharging via the mains, USB socket or vehicle cigarette lighter

A rugged, waterproof casing for intensive, all-terrain use Connections with text and coloured markings to avoid any risk of errors Detection if a hazardous voltage is present, thus prohibiting measurement The CA 6422 & CA 6424 are designed for work in total safety 3 measurement inputs Current measurement: G72 clamp input for CA 6424 3P earth: H, S ,E Battery charger input for CA 6424 Direct access to all the functions, even when wearing gloves Hazardous voltage LED Function keys Cable compensation Operating help indications On/Off button The NOISE symbol flashes if a noise voltage is present,...

CA 6422 & CA 6424 OPTIMIZED USE As soon as it is powered up, the instrument automatically performs a resistance measurement in 2P mode. A short press on the TEST button starts measurements in one-shot 3P mode. A long press on TEST can be used to activate the permanent 3P mode. Internal filtering automatically stabilizes the measurement. As soon as it has stabilized, the result is frozen on the display. A LED indicates the presence of a hazardous voltage which prohibits measurement. If the NOISE symbol flashes, it means that a noise voltage is present. In the event of a noise-filled environment,...
