mode (except
logic, Frequency and Continuity mode)
The default status of the bargraph display is normal mode (from left to
right). The unit of bargraph is 100 counts/bar, except the ZOOM function
mode is in the middle (10 counts/bar). Once this function is pushed, the
bargraph display will change to ZOOM function mode. But under the
PEAK mode, this function is disabled, even if ZOOM function is enabled
first.
The ZOOM function is like the REL mode which is always the difference
between the stored reference and the present reading, and store the
current input value as a reference value.
For instance: If the current reading is 100 counts and will be as reference,
the next step input reading is 200 counts, the bargraph number will be +10
counts, and the 200 counts will be as reference. If the input value is always
the same, the bargraph is zero.
2. Logic mode
In LOGIC mode, this key is used to turn on the buzzer whether is under
High, Low or unknown Logic (the default is High beep).
