SETTING AND OPERATION

■
State transitions
Note 1: Normal indication means display of the instantaneous flow rate, integrated
flow last five digits, integrated flow first four digits, or no-display, depending
on the setting of function setup C04. If an alarm occurs, the alarm code and
normal indication alternate every two seconds.
Note 2: The display turns off automatically after the time specified in C05 has
passed with no key operation. The LED for the instantaneous flow rate
blinks at 4-second intervals (10-second intervals in standby mode) while the
display is off. However, if any key is pressed, the display will turn on again.
Handling Precautions
• Do not press the console keys with a sharp object like a mechanical pen-
cil or needle. Doing so will damage the keys.
