Thank you for choosing the Testboy
The Testboy
TV 222 is intended for measuring CAT III installations and voltages not exceeding
®
300 V (AC or DC) referenced to earth.
Operation
Allow the unit to acclimatise before taking a measurement.
|
When using this clamp meter, the user must observe all the usual safety rules.
When used in the vicinity of equipment that generates interference or noise, the display may
|
show gross errors.
|
Use the appliance only as described in this manual, otherwise the protective devices of this
appliance may be impaired.
Only use the appliance if the housing and pliers jaws are in perfect condition.
|
To avoid damage to the unit, do not exceed the maximum input values specified in the
|
technical data.
Pay attention to this and make sure that the correct measuring mode has been selected.
|
Take special care when working on uninsulated conductors or busbars. (Wear protective
|
clothing if necessary)
Any accidental contact with the conductor may result in electric shock.
|
Take care when working with voltages above 60 V DC or 30 V AC RMS. There is a risk of
|
electric shock at such voltages.
Before switching to other functions, the tongs must be removed from the tested circuit.

electrical contacts and can lead to misleading results. Therefore, other measures should be
taken in addition to ensure that leads do not carry current.
Be careful when working near open exposed ladders or collection ladders. Individual
|
protective equipment should be used.
Do not use current sensors whose wear is already visible in the clamp.
