Functions upgraded from former models
● Four Times More Internal Memory
● Battery Charging Available During Operation
Previously, the battery could be charged only when the
instrument was turned off, but it can now be charged while
measuring. Because of this, if an unexpected power out-
age occurs during long-term measurement and recording,
situations such as measurement discontinuation resulting
from battery self discharge can be avoided, significantly
improving the reliability of long-term measurement.
● Improved Accuracy of Internal Clock
Internal memory has been increased from 8 to 32
megabytes in the new models, which can now store up to
about 16.77 million data points.
● Enhanced Noise Immunity
The circuitry was reviewed from the ground up, and a delta-
sigma type A/D converter was incorporated. The effects
of inverter switching noise and 50/60 Hz hum noise that
previously presented problems have been greatly reduced
by the digital filtering function using the oversampling
principle inherent in this type of device.
Clock accuracy has been greatly improved (0.2 seconds/
day is the same as the previous Model 8422-01).
Note: Optimum noise suppression obtained with recording inter-
vals of two seconds or longer
● Chatter Filter Installed for External Trigger
The filter function installed for external triggering prevents
malfunctioning when starting and ending measurement us-
ing a mechanical relay.
