If the screen saver function is used, it will operate and clear the screen if no operations are performed
during the preset time. If the screen saver operates, press any key to restore the display.
CAUTION
• Condensation may form on the LCD screen if the GL900 is moved from a cold to a warm location. If
this occurs, wait until the LCD screen warms up to room temperature.
• The LCD screen is manufactured to extremely high precision. Black dots may appear, or red, blue,
and green dots may not disappear. Likewise, streaks may appear when viewed from certain angles.
These phenomena are due to the LCD screen construction, and are not signs of a fault.

2.9 Using the Battery Pack (B-517: Option)
The B-517: option battery is the only battery type that can be used with the GL900.
Two battery packs need to be mounted when you have the GL900 run on batteries.
You can also mount only one battery pack when you charge it (using the AC power source). At this time, the
battery pack can be mounted on either the right or left.
The running time using batteries is about 2.5 hours when the screen saver is operating.
Mounting the Battery Pack
(1) While lightly pushing the grip of the battery cover, slid the cover in the direction indicated by
the arrow.

CAUTION
When you have the GL900 run on batteries, be sure to mount two battery packs with the same charge
level.
Do not use a new battery with an old battery at the same time.
If you are not sure about the amount, charge each battery and then attach full-charged two battery
packs.
(3) Attach the battery cover.

Charging the Battery
You can mount either one or two battery packs when you charge them.
Expected time required for charging: • battery pack x 1: approx. 4 hours
The battery pack is charged by mounting it in the GL900, attaching AC adapter to the GL900.
(1) Mount the battery pack in the GL900 (see the previous section for the mounting procedure).
(2) Turn on the power to the GL900. (Please see Section 2.4, "Connecting the Power Cable and
Turning on the Power").
(3) The CHARGE LED lights.
Checks and Preparation
• battery pack x 2: approx. 8 hours
CHARGE LED
CHECKPOINT
• GL900 is equipped with a temperature monitor function which starts automatic charging as soon as it
is cooled down. Therefore, depending on the internal temperature, charging may not be performed
immediately.
When charging is attempted while the power is ON, charging may not be performed immediately
depending on the temperature environment.
In such a case, set the Screen Saver settings to ON. GL900 will start charging as soon as it is cooled
down.
Charging temperature: 15 to 35 °C
• If input is being made directly from the DC power supply instead of the AC adapter, the DC voltage
must be at least approx. 16 V.

Precautions to Observe When Performing Measurement
Please be sure to read the following carefully in order to prevent electric shocks or shorts.
DANGER
• Do not apply voltage of 60 Vp-p or above between the analog input section and main unit (GND terminal), or
between analog input channels.
• Be sure to use only the AC adapter provided as a standard accessory. The rated power supply range for the
adapter is 100 to 240 VAC, and the rated frequency is 50/60 Hz. Do not use any other voltages.
