Operation
Thank you for purchasing the PROMAT CM 100
The PROMAT CM 100 is intended for measuring systems of Category CAT III and for voltages
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, because the protective
|
equipment of the appliance could be impaired.
To prevent damage to the appliance, do not exceed the maximum input values given in the
|
Technical Data.
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.
|
During measurements, place the fingers behind the safety ring.
|
To prevent incorrect measurement values: Change the batteries when the
|
appears.
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.
The "+" sign on the tong indicates the direction of current flow (refer to the Figure).
|
Use extreme caution when working around bare conductors or bus bars. Individual Protective
|
equipment should be used.
Not to use a current sensor if the wear indicator in the Jaw end is visible.
