For more information, go to www.P65Warnings.ca.gov.
1. Working in the vicinity of a lead acid battery is dangerous. Batteries
generate explosive gases during normal battery operation. For this reason,
it is of utmost importance, if you have any doubt, that each time before
using your tester, you read these instructions very carefully.
2. To reduce risk of battery explosion, follow these instructions and those
published by the battery manufacturer and manufacturer of any equipment
you intend to use in the vicinity of the battery. Observe cautionary markings
on these items.
3. Do not expose the tester to rain or snow.

PERSONAL SAFETY PRECAUTIONS:
1. Someone should be within range of your voice or close enough to come to
your aid when you work near a lead acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts
skin, clothing or eyes.
3. Wear safety glasses and protective clothing.
4. If battery acid contacts skin or clothing, wash immediately with soap and
water. If acid enters eye, immediately flood eye with running cold water for
at least ten minutes and get medical attention immediately.
5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6. Be extra cautious to reduce risk of dropping a metal tool onto the battery. It
could spark or short-circuit the battery or other electrical parts and could
cause an explosion.
7. Remove personal metal items such as rings, bracelets, necklaces and
watches when working with a lead acid battery. It can produce a short
circuit current high enough to weld a ring or the like to metal causing a
severe burn.
PREPARING TO TEST:
1. Be sure area around battery is well ventilated while battery is being tested.
2. Clean battery terminals. Be careful to keep corrosion from contacting with
eyes.
3. Inspect the battery for cracked or broken case or cover. If battery is
damaged, do not use tester.
4. If the battery is not sealed maintenance free, add distilled water in each
cell until battery acid reaches level specified by the manufacturer. This
helps purge excessive gas from cells. Do not overfill.
5. If it is necessary to remove battery from vehicle to test, always remove
ground terminal from battery first. Make sure all accessories in the vehicle
are off to ensure you do not cause any arcing.
English

OPERATION & USE:
Note: Each time you connect the tester to a battery, the tester will run a quick
cable verification to ensure a proper connection through the output cables to
sensors in the clamp jaws. If the connection checks out OK, the tester will
proceed to the Home Screen. If the connection is poor, the display will show
“CHECK CABLE”. In this case, check cable connections for visible signs of
damage, as you may need to re-connect the clamps to the battery or replace the
cable end.
PAPER REPLACEMENT
1. Open the paper roll cover.
2. Place a new paper roll in the compartment. Make sure the thermal side is
upside placed as below.
3. Pull a short length of paper from the compartment and press down the
cover to close.
English

Precautions for using the integrated printer:
To prevent from overheating the integrated printer, it is not recommended to
constantly and repeatedly printing the same test result.
The printer should be rested for at least 1 minute if the print has been working for
2 minutes constantly.
Please avoid extremely operating the printer by constantly and repeatedly printing
the same test result.
According to general usage scenarios, it takes about 10~20 seconds to print out a
single result based on the type of the test that is performed.
And the next test is usually completed 20~30 seconds later or more after printing
the previous result.
In this case, the printer will always be cooled down enough and ready for printing
the result of the second test.
If the integrated printer does start to get warm, please have it rested for a while
and cooled down before using the printing function again.
English

HOW TO REPLACE CABLE END:
1. Detach the clamp lead when the replacement is necessary.
2. Make sure the new clamp lead is well connected.
*NOTE that do not detach the cables unless necessary to make sure the pins are
not rusted or corroded by the acid liquid.
INSTALL / REPLACE THE INTERNAL BATTERIES.
The BT2400 offers two difference options for its internal batteries.
A. 6pcs AA alkaline batteries.
B. 2pcs 18650 rechargable lithium batteries.
IMPORTANT:
It is recommended that the user to apply protected type 18650 lithium
batteries instead of unprotected type 18650 batteries.
Because the circuit of the protected type 18650 battery is embedded in the
cell packaging (battery casing) which protects the cell from “over charge”,
heat or “over discharge”, over current and short circuit and less likely to
overheat, burst or start on fire.
English

IDLE TEST RESULTS:
1. HIGH CHARGING VOLTS WHEN TESTING AT IDLE
The voltage output from the alternator to the battery exceeds the normal
limits of a functioning regulator. Check to ensure there is no loose
connection and the ground connection is normal
If there is no connection issue, replace the regulator. Since most
alternators have the regulator built-in, this will require you to replace the
alternator. The normal high limit of a typical automotive regulator is 14.7
volts +/- 0.05. Check manufacturer specifications for the correct limit, as it
will vary by vehicle type and manufacturer.
2. CHARGING SYSTEM NORMAL WHEN TESTING AT IDLE
The system is showing normal output from the alternator. No problem is
detected.
3. LOW CHARGING VOLTS WHEN TESTING AT IDLE
The alternator is not providing sufficient current to the battery. Check the
belts to ensure the alternator is rotating with engine running.
If the belts are slipping or broken, replace the belts and retest. Check the
connections from the alternator to the battery. If the connection is loose or
heavily corroded, clean or replace the cable and retest. If the belts and
connections are in good condition, replace the alternator.
RIPPLE TEST RESULTS:
1. RIPPLE DETECTED NORMAL
Diodes function well in the alternator / starter.
2. NO RIPPLE DETECTED
Ripple is not detected.
3. EXCESS RIPPLE DETECTED
One or more diodes in the alternator are not functioning or there is stator
damage. Check to ensure the alternator mounting is sturdy and that the
