|Operating Switches||START/STOP, ZERO, READ|
|Method of Setting Measuring Conditions||From PC or CF card in which measuring conditions are written beforehand|
|Start/Stop of Recording||From PC, panel switch or ext. contact points|
|Balance Adjustment||From PC, panel switch or ext. contact points|
|LED Lamps||POWER : Lights up when the EDS is turned on.
SYNC : Lights up to indicate synchronization condition.
MEAS : Lights up to indicate measurement in progress.
1, 2, 3, 4 : Lights up to indicate channel status.
READ : Lights up to indicate condition setting in progress.
|Operation Modes||Trigger : START signal from PC or a press of the front panel
START/STOP button starts recording. It stops recording upon recording to a preset number of measured values or when receiving STOP signal from PC or when the START/STOP button is pressed once again.
|Manual||START signal from PC or a press of the front panel START/STOP button lets it wait for trigger signal, and starts recording when the trigger condition is satisfied. It stops recording upon recording to a preset number of measured values. Pretrigger data may be included in the number of measured values by setting.|
|Trigger Source||External trigger signal, analog input|
|Trigger Level||Set for analog trigger mode only,
in the full scale range in plus and minus directions.
|Trigger Slope||Up, down or both
Pretrigger Data Points to be Recorded : Set in a range of 0 to 2000.
|Backup Functions||Setting conditions, balance adjustment data (Saved in the nonvolatile memory)|
Connector : RJ-45 modular jack
