Configuring Input Channels
6
Under
[Threshold]
, select the level used for counting.
1 V
Treats voltages that are greater than or equal to 1.0 V as high level and voltages that
are greater than or equal to 0 V but less than 0.5 V as low level.
4 V
Treats voltages that are greater than or equal to 4.0 V as high level and voltages that
are greater than or equal to 0 V but less than 1.5 V as low level.
7
Under
[Filter]
, select whether to use the
chatter prevention filter.
Set to
[ON]
to prevent false counting due to chatter in mechanical contact (relay) output.
OFF
,
ON
8
Under
[Timing]
, select when to reset counting.
Start
Resets the count to zero at the start of measurement.
Trigger
Resets the count to zero at the start of measurement and at which a trigger activates.
The values acquired before the reset are recorded for the trigger point.
9
Under
[Reset]
, select the operation to perform when the integrated value overflows.
OFF
Stops counting.
ON
Resets the count value and resumes counting from zero.
• You can use the scaling function to convert the integrated pulse count into the measurement
target’s physical properties (Wh, VA, etc.) and display the result.
See “1.5 Using the Scaling Function” (p. 42).
• The upper limit that can be measured is 1,000,000,000 pulses. If the possibility exists that this
limit may be exceeded, it is recommended to perform measurement using the instantaneous
integration mode and integrate the pulses later using Excel
®
or other software.
