The meter was factory-set to the normal mode (integrated flow rate display).

6)

Behavior when a power failure occurs (applicable only for the external powersource type)1)
Power failure detection
When the power source voltage decreases to 8.9 ±0.5 V or less, the meterrecognizes the occurrence of a power failure and then turns off the LCD display andsuspends measurement.
The meter also saves the integrated flow rate and trip flow rate values immediately
before the detection.
2)
Power failure recovery
When the power source voltage increases to 9.4 ±0.7 V or more, the meterrecognizes the recovery of a power failure and then turns on the LCD display andresumes measurement.
The integrated flow rate value immediately before the detection of the power failure
is restored, and the integration is resumed from that value.

Open the inflow valve (upstream from the meter) gradually.
Open the outflow valve (downstream from the meter) gradually.
Check that the pilot is blinking.
Change the indicator display of the meter to an instantaneous flow rate value, and thenadjust the valve so that the flow rate value is in the specified range.
Use the meter in the normal mode with the integrated flow rate display.
At the time of power-on (applicable only for the external power source type), an integrated
flow rate value is displayed.

Depending on the gas to be measured, installation environment, and use conditions, theperformance of the meter can rapidly deteriorate.
Periodically check the meter at the appropriate times in accordance with your usage
conditions.

When the pilot does not blink in spite of the presence of a gas flow, detach the meter fromthe pipes and then gently blow air into the inlet of the meter to check whether or not thepilot on the indicator blinks. If the pilot does not blink, check whether or not foreign objects
adhere to inside the meter. Remove such objects as necessary.
a.
Foreign objects on the rim of the impeller can be removed by giving a light impact
on the body.
b.
Due to the structural restrictions, it would not be possible to restore a meter that has
an adherent such as sealant that cannot be removed on-site. In such a case, youwill need to purchase a new one (i.e. the meter is not repairable).
If the foreign objects can be removed, blow air into the inlet again. When the pilot blinks,
the meter is now properly working.
When the most significant digit of the integrated flow rate display is blinking, it is warningthat the battery is running down (applicable only for the Built-in battery type). It is
recommended that the meter should be replaced immediately.

16 Troubleshooting
In the event you encounter a trouble that could be caused by a failure of the meter, refer to thefollowing table first. If the symptom is not listed in this table or the measures in this table does not
improve the situation, contact your nearest branch office or sales office.
Symptoms
No pulse is output.

Possible causes

Corrective actions

The external connection cable waswrongly wired.

Check that the pulse outputs (unitpulse/high-density pulse) are properly connectedin the correct polarity. Refer to Chapter 9,External connection for how to connect the cable.

The external connection cable has
broken.

Repair the broken part, or replace the external
connection cable.

The connecter part of the external
connection cable has broken because its
sheathed part was rotated during theconnection/disconnection of theconnector.

Be sure to rotate the metal ring at the tip of theconnector.
Since the connector part has broken, the external
connection cable has to be replaced.

The external connection cable waswrongly wired (applicable only for theexternal power source type).

Check that the power source is correct in voltage
and polarity. Refer to Chapter 9, External
connection for how to connect the cable.

The external connection cable has
broken (applicable only for the external
power source type).

Repair the broken part, or replace the external
connection cable.

The circuit board became moist due torainwater or other liquid, which led to ashort circuit.

This product is not a waterproof design. Be
careful not to let water get into the display.

Due to a lightning-induced impulse, an
overvoltage was applied to the internal
circuit board, which caused a breakdown
in the circuit board.

Since the internal circuit board has a failure, themeter main body has to be replaced.

The most significant
digit of the integrated
flow rate display isblinking.

The voltage of the battery has reduced(applicable only for the Built-in batterytype).

The blink indicates that the battery is runningdown.
The meter body has to be replaced.

The display cannot bechanged with a switch.

The switch has broken down because
firm pressure was placed on it with ahard object such as a mechanical pencil
and screwdriver.

Since the switch has broken down, the meterbody has to be replaced. Operate switches with asoft object, such as the tip of a finger.

The circuit board became moist due torainwater or other liquid, which led to ashort circuit and caused themicrocomputer to malfunction.

This product is not a waterproof design. Be
careful not to let water get into the display.

Noises incoming from the external
connection cable caused themicrocomputer to malfunction.

Place the meter away from other signal wires.
Use a shielded wire as the extension wire to theremote indicator. In addition, install a pulse
converter to isolate the transmitter circuit and thereceiver circuit.

The meter is being used out of thespecified flow rate range, so that theactual flow rate cannot be measured
correctly.

Use the meter main body in the specified flowrate range.

The impeller cannot rotate correctly
because a foreign object has adhered tothe impeller.

Following Chapter 13, Instructions for inspection,
inspect the meter main body and remove theforeign object. In addition, clean the inside of thepipes and install a strainer upstream from themeter main body.

The display turns off.

The integrated flowrate value is increasingin spite of the absenceof a gas flow.

- The integrated flowrate value does notincrease.
- The flow rate of themeter main body issmaller than theactual flow rate.

The impeller cannot rotate correctly
because a foreign object in a pipe has
got into the bearing.
The impeller cannot rotate correctly
because drain or water has got into thebearing.

The meter cannot be installed where drain or
water is supplied.
