GL840 series carries two SD memory card slots
SDHC up to 32 GB supported. Captured data can be stored in GBD (Graphtec Binary Data) or CSV file format.
Capturing time* (when all 20 analog channels are being used with Logic/Pulse inputs turned off).

*Figures are approximate. File size of captured data is 2GB in GBD or CSV file format on this chart. Sampling interval is limited by the number of channels in use (10ms:1ch, 50ms:5ch, 100ms:10ch). Limited sampling speed is available when digital sensors and GL100-WL are used as a remote monitoring device.

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)
Accumulating
count mode
Accumulates the number of pulses from the start of measurement
50, 500, 5000, 50k, 500k, 5M, 50M, 500M C/F.S. (Counts/Full Scale)
