Ac Voltage Measurements; Dc Current Measurement - PeakTech 3355 Manual De Instrucciones

5.4. AC voltage measurements

Warning:
Risk of Electrocution. The probe tips may not be long enough to
contact the live parts inside some 230 V outlets for appliances
because the contacts are recessed deep in the outlets. As a result,
the reading may show 0 volts when the outlet actually has voltage
on it. Make sure the probe tips are contacting the metal contacts
inside the outlet before assuming that no voltage is present.
Caution:
Do not measure AC voltages if a motor on the circuit is being
switched ON or OFF. Large voltage surges may occur during the
ON or OFF operations that can damage the meter.
1. Set the function switch to the "V" position.
2. Press the "MODE" button until "AC" appears in the display.
3. Insert the black test lead banana plug into the negative COM
jack and the red test lead banana plug into the positive V jack.
4. Touch the test probe tips to the circuit under test.
5. Read the voltage in the display. The display will indicate the
proper decimal point, value and symbol.

5.5. DC current measurement

1. Insert the black test lead banana plug into the negative COM
jack.
2. For current measurements up to 4000 µA DC, set the function
switch to the "µA" position and insert the red test lead banana
plug into the mA-µA jack.
