3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1 Simulate the human body load
Access impedance instrument input 200ohm resistor in series with the capacitor 0.022µF as simulate the human load.
3.2 The best balance
When the instrument input of an analog of human access to the load, the adjustable impedance instrument bridge balance arm of the instrument to achieve the best balance, this time the bridge
Arm impedance called the best balance.
3.3 Worst balance
When the instrument input of an analog of human access to the load, the adjustable impedance instrument bridge balance arm of the instrument at the upper edge of the equilibrium range,
In this case the bridge arm impedance called the worst balance.
3.4 Working condition
When the instrument bridge balance, after access to a imbalance in impedance, the instrument enters the record or display the status of the waveform.
3.5 Top working condition
The instrument is the best balance into the working state.
3.6 Worst Job Status
The instrument is the worst balance Enter working condition.
