Streptococcus sp. and Staphylococcus aureus are the most common etiologic organisms of cellulitis and usually respond to empiric antibiotics. A seven- to 10-day regimen is the recommended treatment. However, uncomplicated cellulitis has a strong inflammatory response with a low yield for bacteria in the affected area.
Multimeters are generally not autoranging. You have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if youâve measuring a 12V battery, use the 20V setting.
The most common use of this setting is to test remaining battery voltage, alternator output, power to a car radio, amplifier, etc. AC Voltage (V~ with a wavy line): In the meter pictured, AC Volts is written, not expressed as a symbol. This meter has a 200V setting and a 750V setting.
