The
CAL-50 is a battery operated accessory providing a 50 µV (±2%)
DC differential calibration signal for up to 40 AS40 AC channels (Grass
Comet EEG and Comet PSG), or up to 20 AURA-PSG AC channels.
Modes |
| •
|
Automatic,
where a repetitive signal is produced: first a 50 µV level for
approximately 6 seconds, then a zero µV level for 6 seconds. |
| •
|
Manual,
where a 50 µV level is produced for as long as a pushbutton
is pressed, followed by a zero µV when the pushbutton is released. |
|
The convention
of “G1 Negative” is used in both modes.
