conditions. If the ambient temperature exceeds normal and safe operating limits of 50° F
to 95° F (10° C to 35° C), charging stops. In most situations, charging automatically
resumes when the ambient temperature is within normal and safe operating limits.
• Use the external AMS 2140 Battery Charger only in a non-hazardous area.

Battery Charger
You can charge your battery pack separately from the analyzer. You can use the charger
indoors, or you can use the automobile power supply cord to charge your analyzer in your
car. You can charge one battery pack at a time. A full recharge may take 3 hours.
Note
If the battery pack is in storage mode, placing the battery pack on the charger will activate the
battery pack.
WARNING!
• Use only Emerson-supplied power supplies and chargers approved for use with the AMS
2140 and Emerson battery packs. Using any power supplies and chargers other than
approved Emerson power supplies and battery packs could not only void the warranty,
but will also most likely damage the analyzer or the battery pack.
• Ensure the air vents on the external AMS 2140 Battery Charger are clear and uncovered.
• When charging the AMS 2140 with the battery pack or the battery pack by itself, ensure
the ambient temperature where charging is occurring is 50° F to 95° F (10° C to 35° C).
• Charge the battery pack only in a non-hazardous area.
Prerequisites
Remove the battery pack from the analyzer. See Section 2.7.6.
Procedure
1. With the metal contacts on the battery pack facing up, lift the battery pack over the
raised edges and then slide the battery pack into the charger.

Insert the power supply cord into an outlet and into the connector on the back of
the external AMS 2140 Battery Charger.
Charging begins and the LED is amber. The battery pack is fully charged when the
battery LED on the external AMS 2140 Battery Charger changes from amber to
green. To check the progress, press the button on the battery pack next to the 5
LEDs. Each LED represents approximately 20 percent charge
To remove the battery pack, lift up the battery pack to clear the two raised edges,
and then slide out the battery pack

intensity based on the light in your environment. You can disable the automatic
adjustments. You can set a timer to disable the backlight after a period of inactivity. See
Section 2.14.3.
Note
A higher backlight intensity decreases the battery pack life. For optimum battery pack life, set the
