(7) After replacement, enter the replacement date in the space
marked “Date” at the bottom of the unit change label, and
attach the label to the
MCF
.
Handling Precautions
• The measurement accuracy is ±5 % FS ±1 digit after the measure-
ment module is replaced with a new one.
• When replacing an RS-485 communications model or a 4 to 20 mA
output model with a battery model, or vice versa, make sure that there
are no wiring errors before turning on the MCF.
Note
• Flow path identifier.
The flow path identifier is a property of the main path. It refers to the diver-
sion ratio adjustment of the main path. The flow path identifiers 0 to 2 corre-
spond to diversion ratio adjustments 0 to 2. If the flow path identifier is reg-
istered in the measurement module in maintenance mode, the
MCF
can
adjust the output for the properties of the main path. Therefore the
MCF
is
able to maintain accuracy.

Maintenance of battery box
(1) If the MCF will not be used for a long period, store it without the batteries to
prevent battery leakage problems.
(2) Do not replace the batteries when the MCF is wet. Take care to prevent entry of
water or dust when replacing the batteries.
(3) Do not replace the batteries when the MCF is in use.
(4) If the battery alarm is activated, replace the batteries as soon as possible.
(5) Check regularly for a battery leak or other problems.
(6) If the batteries are dead, remove them.
(7) During battery replacement, the integrated flow value may not accumulate for
up to 10 minutes. Similarly, in the case of an integrated countdown, the value
will not be counted down during this time.
(8) After battery replacement, check the battery level on the device information dis-
play.
(9) After replacement of the batteries, make sure that the U bolts or mounting bolts
which hold the battery box are not loose. If they are loose, retighten them.
