Información
The model 168 is a versatile autoranging Digital multimeter useful for measurement of ac and dc voltage, ac and dc current, and resistance. Voltage measurements can be made from ±0,0001 volt to ±1000 volts dc or 0.0001 volt to 500 volts ac. Current measurements can be made from 0.0001 mllliampere to 1 ampere ac and dc in two spans. Resistance measurements can be made from 0.1 ohm to 20 megohms in two overlapping spans. Range and polarity is automatically selected. In addition to the display of digits, the 168 indicates decimal point, function (AC or DC), and measurement unit (mA, A, kΩ, MΩ).
