Trigger,
Alarm function
Trigger actionStart or stop capturing data by the trigger
Repeat actionOff, On (auto rearmed)
Trigger sourceStart: Off, Measured signal, Alarm, External, Clock, Week or Time
Stop: Off, Measured signal, Alarm, External, Clock, Week or Time
Condition SettingCombination: OR or AND
Analog signal: Rising (High), Falling (Low), Window-in, Window-out
Logic signal: Pattern (combination of each input signal in high or low)
Pulse (number of count): Rising (High), Falling (Low), Window-in, Window-out
Alarm outputOutputs 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)
Instant count
mode
Counts the number of pulses per sampling interval
50, 500, 5000, 50k, 500k, 5M, 50M, 500M C/F.S. (Counts/Full Scale)
Calculation
function
Between channelsAddition, Subtraction, Multiplication, and Division for analog input
StatisticalSelect two calculations from Average, Peak, Maximum, Minimum, RMS
Search functionSearch for analog signal levels, values of logic or pulse or alarm point
in captured data
Interface to PCEthernet (10 BASE-T/100 BASE-TX), USB (Hi-speed), WLAN (using B-568 option)
Storage
device
InternalBuilt-in 4GB Flash Memory *6
ExternalOne SD card slot (Support SDHC memory card, up to 32GB) *7
Saved contentsCaptured data, Setting conditions, Screen copy
Capturing modeMode: Normal, Ring, Relay
Ring: Saves most recent data (Number of capturing data: 1000 to 2000000 points) *8
Relay: Saves data to multiple files without losing data until dada capturing is stopped
Replay dataReplays captured data that was saved in the GL840 (in GBD or CSV format)
Scaling (Engineering unit) functionMeasured 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
