1. PRESENTATION
The "C100" series clamps are designed to measure alternating currents, on low and medium-powered
installations, from 0.1 A to 1200 A ~ for certain models. See 4. Characteristics).
They can be used on all multimeters, wattmeters, recorders or oscilloscopes for the C160. According to
model (see 4.2) : single or multi-calibre output, alternating current or alternating voltage.
They have dual insulation or reinforced insulation and comply with international norms, particularly
EN 61010-2-032 “ammeter clamps”. (See 4.6.)
2. DESCRIPTION
(See drawing in 6. Appendix)
➊
Output: Ø 4 mm sockets or lead (according to model) : lead length : 1.5 m and 2 m for the C160.
➋
Ratio switch for multi-calibre models.
➌
The raised arrow on top of the clamp jaw indicates the direction of the current flow. The current is
considered to flow in the positive direction when it flows from the current producer to the current
consumer. This clamp orientation is necessary when measuring power (measuring current in parallel
with voltage).
