1
Frequency measurement can only be done in auto range mode. Specications are for 30 minutes warm-up time, using one second aperture.
Measuring method is using reciprocal counting technique with AC coupled input at AC voltage function. Gate time of 0.1 second or 1
second.
2
Only applicable for square wave measurement.
