Protection devices

ASYC II series instruments are fitted with various protection devices :

A protection by varistors allows a chopping of transient overvoltages present at
the terminals of measurement.

A PTC (Positive Temperature Coefficient) resistor protects against permanent
overvoltages of up to 600 V during resistance, capacitance and diode test
measurements. This protection is reset automatically after overload.

One F1 intrinsically safe fuse provides protection during current measurements.

A special intrinsic safety case ensures IP 67 sealing.
1.3.

Safety devices


The battery unit and fuse cannot be accessed without first disconnecting the
measuring leads.

When measuring voltages above 24 V, the sign blinks

If the maximum range is repeatedly exceeded, an intermittent audible signal
indicates the risk of electric shock.
