Oscilloscope clamp

5.1. Precautions

 Do not exceed the voltage of 300V (CAT III) or 600V (CAT II) with respect to
earth with an uninsulated conductor.
 Use the clamp on conductors in which the current is less than or equal to the
maximum continuous value allowed, namely 100Arms or 140A peak.
 Do not expose the clamp to running water or spattering.
 Keep your hand and fingers behind the guard.
If the housing of the product is cracked or broken, and/or the front panel with the

buttons separates, there is a risk of electrocution; make sure that the product is
not used in that condition, and replace it or have it repaired.

5.2. Use

 Adjust the DC-Zero.
 Press the trigger to open the jaws of the clamp, then place the clamp on the
conductor with the current in the right direction (source P1 towards the back of
the arrow, receiver P2 towards the tip of the arrow).
 Close the clamp. Make sure that it is correctly closed and centred on the
conductor, in order to obtain optimum measurement accuracy.
 The pass band can be modified on demand: 1MHz, 30kHz, 3kHz.

5.3. Maintenance

Before any maintenance work is done, the clamp must not enclose a conductor; it must
also be disconnected from the external instrument to which it is connected.
 Maintenance of the magnetic circuit
Keep the air gaps of the clamp perfectly clean.
Wipe them, if necessary, with a soft cloth.
 Maintenance of the housing
Clean the clamp with a cloth moistened with soapy water and rinse with a cloth
moistened with clear water. Never run water on the clamp.
Dry using a dry cloth or forced air (max. temperature +70°C).
 Check of the calibration
Annual verification of the measurement characteristics by an approved
organization.
