Battery Monitoring Circuitry
A standard feature of Alpha 4314 is a circuit that monitors the output voltage of the internal battery
supply. The Battery Status LED for this feature is located to the far left of the display window.
•
A green Battery Status LED indicate that the batteries are charged and the device can be used.
•
A flashing Battery Status LED between green and red, indicates that the batteries will require
recharging within the next ½ hours of continuous use. Readings are still within specified accuracies
at this point.
•
A Red Battery Status LED indicates that battery is low and that readings should not be trusted. An
overnight recharge should be performed before using the Alpha 4314 for critical testing.
NOTE: It is possible for the user to receive a low battery indication on a single range only (particularly the
20Ω range), while the Alpha 4314 remains well within operating limits on other ranges.
Unless the user
observes a continuous low battery indication during measurement, readings are still valid.
Range Indicator LEDs
The Alpha 4314 can have 4 of 8 possible ranges. The ranges installed are indicated on the front panel by
a series of lit LEDs. The range that is selected during measurement is indicated by a GREEN
LED.
