Using the formula: V = S X D What is the voltage of the waveform with peak to peak amplitude measurement of 18 mm, if the sensitivity is set at 7uV/mm?

126 uV

Using the formula: D = V / S How much deflection will occur if the calibration input is set at 100uV and the sensitivity is set at 7 uV/mm?

14 mm deflection

Using the formula: D = V / S How much deflection will occur if the calibration input is set at 20uV and the sensitivity is 7uV/mm?

3 mm deflection

Using the formula: V = S X D Calculate the voltages of a discharge that measures 7 mm in amplitude, and the sensitivity is set at 7 uV/mm.

49 uV

Using the formula: D = V / S How much deflection will occur if the calibration input is set at 50uV and the sensitivity is set at 7 uV/mm?

7 mm deflection

True or False: If the waveform blocks, increase the sensitivity of the amplifier so that less deflection will be required to represent more voltage.

False

The ______ the μV value the less sensitive the amplifier.

Larger

The ______the μV value the more sensitive the amplifier.

Smaller

How does "Digital Bio Calibration" differ from traditional analog "Bio Cal"?

The "Digital Bio Cal" montage records every recording electrode used in Input 1 and the system reverence in Input 2, thus viewing the input from each electrode placement and each amplifier that the instrument will use when making the EEG recording.

True or False: If the incoming voltage exceeds this dynamic range, the waveform will block at the upper and lower limits causing high voltage waveforms to block or square off.

True
