*1: At least 1 unit is required for the GL840, so up to 9 units can be connected.
*2: Logic/pulse cannot be used when the GLT400 is used in REMOTE mode.
*3: When the sampling interval is set faster than 500 ms in REMOTE mode, the real-time waveform
display, calculation between channels and trigger detection, etc. are delayed because the data of the
GLT400 is sent all together to the GL840 at intervals of 500 ms.
*4: The digital display value when the sampling interval is set faster than 500 ms is the calculation result
at the 500 ms interval. The captured data are the calculated value at the sampling interval.
*5: In REMOTE mode, the operation settings are performed from the GL840 base unit, so the settings of
the GL840 are overwritten.
