Common mode rejection ratio
90 dB or more (50/60 Hz; signal source 300Ω or less)
Noise
48 dB or more (with +/– terminals shorted)
Filter
Off, 2, 5, 10, 20, 40
Filter operation is on a moving average basis.
The average value of the set sampling count is used.
If the sample interval exceeds 30 seconds, the average value of data obtained in a sub-
sample (30 seconds) is used.
* Even when connected to the GLT400, the ambient temperature is the range of 0 to 45°C.
