During Use - KPS MT40 Manual De Funcionamiento

KPS-MT40 • Digital multimeter
When the ground voltage of open circuit voltage exceeds 250V, do not try
to make current measurements on the circuit. If the fuse is blown when
making a measurement, you may damage the meter or injure yourself. To
avoid damage to meter or device, before measuring current, please check
the meter'sfuse. When measuring, you must use the correct input socket,
function and measuring range. When the test probe is inserted to the current
input socket, don't connect the other end of the test probe with any circuit
in parallel.
To avoid wrong readings, electric shock or personal injury, when (
pears on the meter display, replace the battery immediately. Use only a fuse
with specified amperage, fusing rated value, voltage rated value and fusing
speed (F250mA/250V, FF10A/500V) To avoid electrical shock or personal
injury, before opening the battery cover to replace battery, you should turn
the meter off and make sure that the test probe is disconnected from the
measurement circuit.

1.1.2 During use

• If the meter is used near a source of significant electromagnetic interference,
meter readings will become unstable and have large errors.
• Don't use the meter or probe when it is broken.
• If you do not use the meter in accordance with the instructions, safety
functions provided by the meter may become invalid.
• When you work around the bare conductor or bus bar, you should be extre-
mely careful.
• Do not use the meter near explosive gas, vapor or dust.
• Measure known voltage with meter to verify that the meter is working pro-
perly. If the meter is working abnormally, do not use. Protective equipment
may be damaged. If there is doubt, the meter should be sent to repair.
• The meter should be used with correct input, function and measuring range.
• When you can't determine the size range of signal to be tested, please
