BATTERY SYSTEM TESTER
1.Brief Introduction
DI-216/DI-217 battery storage testers are used for
activated style lead-acid storage battery, along with checking
the following conditions of the battery, starting up, charging,
and electrical loading. With great design, easy operation,
precise reading, complete functions, this tester supply the
readings by a large LCD and hints by sound and light when
testing. Precise circuit and strong digital processing unit make
it complete collection of a series of complicated data and figure
out every test data, which availably by 4-wire Kelvin test
connection. Besides it strengthens input protection inside , in
order to prevent such situations as polar reversal connection ,
over-high voltage input, poor contact of the test clamps and so
on. That makes sure safer and more convenient when testing.
This tester is the best tool for battery sales, vehicle repair
and condition check of all kinds of lead-acid batteries that used
in equipment system associated with lead-acid battery.
2.Safety Rules And Attentions
This manual includes instruction, operation warning and
maintenance. It is possible to damage the tester without
regulations in this manual. This tester is designed and
produced strictly according to GB4793.1 electronic
measurement instrument safety requirement and
IEC/EN61010-1 safety standard. It also reach double insulation
over voltage standard CAT

600V and pollution degree 2 .
(1) DI-216/DI-217 is available to vehicle of 12V storage battery.
(2) The working voltage of DI-216/DI-217 is DC 9V to 18V. Make
sure do not check the series connection battery.
(3) The voltage value will be higher than that in the normal
situation after the checked battery being fully charged . Please
turn on the headlights for 2 to 3minutes, then check the battery
when it’s voltage value drop to the normal value.
(4) Check the insulating layer of the clamps before measuring.
Damage, bareness and disconnection are unacceptable. It is
8-2 It is unavailable to know the electric quantity of
storage battery by intuition
Hydrometer can be used to check the condition of the
battery. Battery water is distilled water and pure sulfuric acid of
the proportion of 1.260/20°C to allocate. For a new battery, it is
supposed to supply distilled waterwith reduction of battery water
for the reason that the degree of acid is fixed when the quantity
of battery water remain the normal range. Distilled water
supplement can maintain a certain amount of water, but alsothe
PH value. If the battery works normally, in addition to the PH is
fixed, the proportion of the value will be in a certain range.
If the battery finishes charging, the proportion of battery
water does not reach 1.26-1.28, along with the tested voltage
under 12.7V, the storage capacity of this battery has descended.
It is impossible to recover its life by deliberately adjusting the
proportion to 1.26 (Increase the sulfuric acid water), on the
contrary shorten its life fast for the reason that it will increase
the acidity of battery water, not the voltage however.
