12.2 Individual Test Pin Functions
NOTE:
Connect the 0V end to the TP-pin of the electronics unit.

WAVEFORM
FWD
An output of No. 1 amorphous sensor waveform appears.
10μs
200mV
200mV
REV
An output of No. 2 amorphous sensor waveform appears.
While the flowmeter is making forward revolutions, pulses are
produced slightly behind the FWD pulses.
Same as above.
PLS
A rectangular waveform after FWD pulse waveshaping
appears. Timing remains the same as that of FWD and its
waveform is one before unfactored output amplification.

3V
IN
Accepts a square-wave pulse train from the pulse checker
(OVAL Model PC2201, for example). Used for analog full scale
adjustment, loop check, or other servicing. input mode is
Model PC2201's PG30 mode. Also accepts pulses with levels
"0": 1V max. and "1 ": 7 to 12V min., or open collector.
OUT1
Provides a waveform corresponding to the power signal which
appears across remote output signal terminals 1 and 2.

Factored pulse
Depends on "Pulse width"
setting.
③

OUT2
Produces a waveform corresponding to the open collector
output which appears across remote output terminals 3 and 4.
12.3 About the Meter Factor
If it is desired to change meter factors in an instrumental error testing, for example, you may establish a new
meter factor by the following procedure.
Instrumental error testing must be conducted with proper facilities and procedures specified in the Weights and
Measures Law, Japanese Industrial Instruments Federation, JIS standards, or other established standards.

How to Determine a New Meter Factor
New Meter Factor = (Current meter factor) x (1 -
E
100
) (mL/P)
where current meter factor: Stated in the test report or on the tag of the product.
E: Instrumental error determined by the test (%)
IMPORTANT: The new meter factor should be put on paper for later reference.
