■ Indicator value•The number of digits for m3 is 4, while for the decimals (liters) it is 3.■ Shutoff indication• is displayed when the shutoff valve is in the “Closed” position.•The “ガス止” (Gas Stop) indicator ashes at 1 Hz (ON for 0.5 second and OFF for 0.5 second) during a shutoff when the recovery operation is impossible.•The display position should be at the upper left of the indicator value.■ Flow pilot•The ow rate pilot display is lit when gas ows under the conditions shown on the right.• is displayed at the display position at the upper right of the indicator value.■ Event•An identication display appears whenever something goes wrong with the meter.•The display position should be at the upper right of the indicator value.■ Meter status display•The following two modes are provided for displaying the indicator “▲▲▲▲” (“▲” ON, “△” OFF)1) Internal status display modeIndicates the various internal states of the meter except during recovery leak check.DisplayStatus nameON timingOFF timingLeft ▲SleepingIn the shipment modeIn the non-shipment mode▲When an internal pipe leak alarms has occurredWhen the internal pipe leak alarm is cleared▲Pilot light registrationWhen registration pilot light ow rate 1 is registeredWhen all registration pilot light ow rates are deletedRight ▲Recovery failureWhen shut down due to a recovery leak check failureWhen recovery leak check is started* When “▲ (Recovery failure)” is lit, the event display indicates the shutoff event before recovery leak check. However, if a new shutoff event occurs during the recovery leak check, the latest shutoff event is displayed.2) Recovery leak check display modeIndicates a failure to recover and the progress of the operation during recovery leak check.DisplayDescriptionRecovery check display▲▲▲△LitWhen recovery leak check is startedRecovery leak check display▲▲▲△Flashing△▲▲△Flashing△△▲△FlashingEvent display “L” ashesThe ▲ display is turned off in sequence starting from the left whenever 1/3 of the operation time to determine a pressure drop elapses.(Displays the elapsed time.)Flashing time: 0.5 second, OFF time: 0.5 second.△△△△*1When recovery leak check is successful*1: Preceding Item 1) Changes to the internal status display mode.▲▲▲▲ ↓↑Flashing△△△△↓△△△▲*1Flashes for 5 seconds when recovery leak check fails.(ON time: 0.5 second, OFF time: 0.5 second, repeated 5 times.)After ashing ends, “▲ (Recovery failure)” is lit.*1: Preceding Item 1) Changes to the internal status display mode.Meter LCD displayMeter status displayShutoff indicationFlow pilotIndicator valueEvent120 seconds to go60 seconds to go0 seconds to goRecovery (index value)■ Recovery leak check time is now “visible”.Gas ow rateMore than 1,000 L/hMore than 200 L/hLess than 1,000 L/hMore than 70 L/hLess than 200 L/hMore than 15 L/hLess than 70 L/hMore than 4.5 L/hLess than 15 L/hTime to turn on (approx.)4 seconds8 seconds10 seconds20 seconds30 secondsUH Meter Display Functions39UH Meter Display Functions
