(7-5) Bargraph display
The bargraph displays 10 times speed comparing with numeric display. However it is not displayed in frequency,
revolution and capacitance measurement mode
measurement mode, " 4000 " is displayed in capacitance measurement mode, and also every digit blinks in
these modes.
over-range occurs by the absolute input value
In cases of the “ 0 “ display value, AC voltage, AC current, resistance (
frequency ( f ), tacho ( rpm ) and continuity test (
However in relative measurement mode, any measurement modes display " – " .
(7-6) Over-range Display
(7-7) Polarity Display
However " 0000 " is displayed in frequency measurement mode, " 60000 " is displayed in revolution
In relative measurement mode, but it is not concerned with the display value. All of digits blink when
When the over-range is occurred, the display becomes " 40000 " and all digit blinks.
1. BP-
2. BP0
3. BP1 to 40
4. The figures of " 0, 10, 20, 30, 40 " under the bargraph is displayed expecting for frequency, tacho
and capacitance measurement mode.
: Displayed when negative signal is input.
: Displayed when the digital display is more than about " 00400 ".
: BP1 is displayed when the digital display is more than about
" 01000 ", then 1 segment display increases at every 1,000 counts.
If overflow occurs, all of BP0 to BP40 are displayed.
) measurement mode, " – " mark is not displayed.
