    I found here some precautions while using pipette and burette.
    http://www.thestudentroom.co.uk/wiki/Revisiondexcel_Chemistry_Unit_3B_-_Laboratory_Techniques_-_Volumetric_Analysis


    Can you give me some precautions required while using these apparatus (for example checking for zero error in micrometer and vernier calipers):


    Air track
    Ammeter
    Balance (beam, pan)
    Cathode ray oscilloscope
    Gold leaf electroscope
    Laser
    Light gates
    Loudspeaker
    Meldi’s experiment
    Meter scale
    Micrometer screw gauge
    Microphone
    Ohmmeter
    Ripple tank
    Signal generator
    Sonometer
    Stopwatch
    Temperature sensor
    Thermometer
    Vernier caliper
    Vibrator
    Voltmeter

    I am weak in the precautions section of the AS practicals, so help will be appreciated a lot.

    When using a micrometer screw gauge, always remove your finger before tightening it up.

    Do not attempt nasal insertion of microphone.

    Resist the urge to measure your own body's resistance with a multimeter.

    Try not to drown in a ripple tank.
