2. Preparation
2.3 Setting the Date and Time
After installing the batteries, set the date and time. Note that if the power is turned off
before completing minute setting, start with the date setting when you turn on the power
next time. By replacing the batteries, the date setting is not affected but the time setting
is. So the time must be reset.
Note: If a sensor cable is not connected to the meter, fluctuating readings or an error
message may appear. Before pressing POWER key, make sure that a sensor has
been connected.
• Setting Procedure
After installing the batteries, press and hold POWER key for at least one second. All
LCD segments appears momentarily and then the date setting display starts
automatically. Set year, month, day, hours, and minutes following the flowchart below.
Note: If you attempt to abort the setting procedure before completing, the meter will
beep three times and reject the attempt. Continue until the minute setting is
completed.
