How to check the battery tester?
You will need:
  • Tester
  • probes with wires for Tester
  • Batteries
# 1

To check the battery charge level applied measuring instrument multimeter (tester).there are a few rules for proper evaluation of health of the battery: the battery voltage is checked by tester, when the switch is in position "B" (volt) DC.Probes are closed tester on the battery poles.The display will show the meter readings, the figures will indicate the voltage measured by the battery.This measurement is not accurate, since the voltage should be checked when the load resistor in the circuit.If such a test device often shows a complete battery charging, but when using the element quickly discharged (sets).

But how to check the battery correctly?The best and most accurate results on the battery performance is determined by measuring its current strength.Attention!This method never try to check lithium-ion and lithium-polymer batteries, which may cause them to explode or catch fire, may damage the hands and fire!O

n the other battery check is made at fault pole element at a time from 0.5 to 2 seconds, as this method of verification element can be quickly discharged and fail as a short circuit occurs.

Put the tester switch is set to "DC" - Amps in the area of ​​the biggest limit of the current measurement.Probes shorted to the battery poles just for a moment, until the numbers on the scoreboard will not stop.Fixing the gaze readings, the circuit is opened immediately.

Now you know how to check the battery tester, but how to determine its efficiency?Batteries with the parameters from 0.5 to 1 Ampere (short circuit current) can you serve remote controls.Intact batteries have approximately the following parameters: common batteries have a voltage of 1.5 V 2 - 2.5 A, 12 V batteries at least 2.5 A, for high-capacity batteries, such as Energizer and Dyurasel 4 - 4,5 A Note: in some models of testers for measurement of current is necessary to rearrange the probe to a different slot, other than that through which the voltage is measured.Look in the manual of the device.
