that do not exceed the reference to earth 600 V (AC or DC).
Operation
Before taking a measurement, allow the appliance to acclimatize.
|
When using this tong meter, the user must adhere to all usual safety regulations.
|
When using in the vicinity of appliances that cause interference or noise, the display can
indicate gross errors.
|
Only use the appliance as described in these operating instructions, otherwise the protective
equipment of the appliance could be impaired.

Pay attention to the function switch and make sure that it is set at the correct position before
each measurement.
|
Particular attention must be paid for tasks on naked cables or busbars.
|
Every inadvertent contact with the conductor can result in an electric shock.
|
Caution when working with voltages of more than 60 V DC or 30 V AC RMS. At such voltages,
there is the danger of electric shocks.
|
Before switching to other functions, the tongs must be removed from the circuit to be tested.

Before each measurement, ensure that the test appliance is fully serviceable. Before using the
appliance, test the function using a known, functional source of power.
|
Test on a known live source within the rated ac/dc voltage and current range of the product,
both before and after use to ensure unit is in good working condition.
