Operation

Thank you for purchasing the Testboy
The Testboy ® TV 217 is intended for measuring systems of Category CAT III and for voltages that
do not exceed 600 V (AC or DC) in an earthed state.
Operation
Before taking a measurement, allow the instrument to acclimatize.
The user must comply with all the usual safety regulations when using this clamp meter.
|
The instrument can indicate gross errors if it is used in the vicinity of appliances that cause
|
interference or noise.
Only use the instrument as described in this manual; failure to do so could impair its protective
|
equipment.
Only use the instrument if the housing and clamp jaws are in a faultless condition.
|
To prevent damage to the instrument, do not exceed the maximum input values specified in
|
the technical data.
Pay attention to the function selection switch and make sure that it is set to the correct
|
position before each measurement.
Exercise especial caution when performing tasks on naked conductors or busbars
|
(wear protective clothing if necessary).
Any inadvertent contact with the conductor can result in an electric shock.
|
Exercise caution when working with voltages greater than 60 V DC or 30 V AC RMS. Such
|
voltages pose a danger of an electric shock.
The clamp must first be removed from the circuit to be tested before switching to other
|
functions.
Ensure that your fingers are behind the safety ring during measurement.
|
To avoid incorrect measured values: Change the batteries when the
|
Ensure that the test instrument is in faultless condition before each measurement. Test the
|
function using a known, functioning power source before using the instrument.
Always discharge the capacitances and disconnect the instrument to be tested from the power
|
supply before performing diode, resistance or continuity measurements.
Insecure connections with the installed electrical contacts mean that voltage tests performed
|
on sockets can pose problems and produce misleading results. Additional measures should
therefore be taken to ensure that the lines are not live.
Exercise caution when working in the vicinity of exposed accessible conductors or busbars.
|
Use personal protective equipment.
Do not use a current measuring sensor with visible wear on the clamp.
