|
|
| Alarm output | Outputs a signal when alarm condition occurs in the input signal *5 | Pulse input
function | Rotation count
(RPM) mode | Counts the number of pulses per sampling interval and converts to rpm
(rotations per minute), Number of pulses for one rotation can be set to
50, 500, 5000, 50k, 500k, 5M, 50M, 500M rpm/F.S. (rpm./Full Scale) | |

Calculation
function | Between channels | Addition, Subtraction, Multiplication, and Division for analog input | | Statistical | Select two calculations from Average, Peak, Maximum, Minimum, RMS | | Search function | Search for analog signal levels, values of logic or pulse or alarm point
in captured data | |
| Interface to PC | Ethernet (10 BASE-T/100 BASE-TX), USB (Hi-speed), WLAN (using B-568 option) | Storage
device | Media | SD memory card (Support SDHC, up to 32 GB), supports 2 slots *6 | | Saved contents | Captured data, Setting conditions, Screen copy | | Capturing mode | Mode: Normal, Ring, Relay
Ring: Saves most recent data (Number of capturing data: 1000 to 2000000 points) *7
Relay: Saves data to multiple files without losing data until dada capturing is stopped | |
|
| Replay data | Replays captured data that was saved in the GL840 (in GBD or CSV format) | | Scaling (Engineering unit) function | Measured value can be converted to specified engineering unit
• Analog voltage: Converts using four reference points (gain, offset)
• Temperature: Converts using two reference points (offset)
• Pulse count: Converts using two reference points (gain) | |
|
|
| Action during data capture | • Displaying past data (using dual display mode (Current + Past data))
• Hot-swapping the SD memory card
• Saving data in between cursors | |
