18.1 If a Problem Occurs

Dealing with Unusual Circumstances

• If a message appears on the screen, see the following pages for reference.
• If servicing is necessary or the AQ1200 does not operate properly even after you have attempted to

deal with the problem according to the instructions in this section, contact your nearest YOKOGAWA
dealer.

Symptom

Solution

Reference

Even when the power is

on, nothing appears on

the screen.

If you are using an AC adapter, make sure that the plug is connected firmly to the outlet,

the power cord is connected firmly to the AC adapter, and the AC adapter’s DC plug is

connected firmly to the AQ1200.

—

1

If you are using a battery pack, make sure that it is attached firmly.

—

1

Charge the battery pack, and make sure that the ON lamp is illuminated.

18.7

The LCD turns black at high temperatures. At low temperatures, its display speed becomes

slower. Make sure that the temperature of the area where you are using the AQ1200 is

within the operating temperature range.

—

1

The display disappears

after time passes.

The AQ1200 turns off automatically when its battery is low. Check the remaining battery

power.

18.7

If you have specified a time for the Power Save setting, the AQ1200 will turn off

automatically if no operations have been performed for the specified time. Check the

settings.

17.2

The screen is dark.

The screen is dark when the LCD Brightness setting is set to “Power save.” Check the

settings.

17.2

The LCD may be worn out. Servicing is required.

18.11

When the temperature of the AQ1200 or its battery pack is high, the AQ1200 lowers the

LCD brightness automatically to prevent damage. Make sure that the temperature of the

area where you are using the AQ1200 is within the operating temperature range.

—

1

The power turns off

automatically while the

AQ1200 is being used.

The AQ1200 turns off automatically when it detects an error. A warning message will

appear when this happens. Read the message. Fix the problem indicated in the message,

and then turn on the AQ1200.

18.2

2

The battery pack cannot

be charged.

The battery pack temperature may be too low or too high. Make sure that the temperature

of the area where you are using the AQ1200 is within the operating temperature range.

Remove the battery pack from the AQ1200 and let it sit for awhile in a room temperature

environment.

—

1

The battery pack may be reaching the end of its life expectancy. Replace it with a new

one.

18.11

The power turns off

automatically while the

AQ1200 is starting.

You may have accidentally pressed the power switch twice.

—

1 See the operation guide, IM AQ1200-02EN.
2 When it is likely that the usage limitations of the AQ1200 will be exceeded, the AQ1200 will display a

warning message and turn off automatically to prevent damage. For the conditions under which messages
appear, see section 18.2.
