metracell bt pro

Battery systems, such as those used in uninterruptible power supplies (UPS), are an important part of critical application scenarios that minimize the risk of failure and ensure smooth operation of power supplies, e.g. in healthcare facilities and data centers.

The Metracell BT Pro is a versatile, portable and versatile test instrument for the evaluation and maintenance of battery systems and uninterruptible power supplies based primarily on lead-acid batteries. Lead-acid batteries account for more than 75% of all rechargeable energy storage devices currently in use, and since large capacity energy storage must be used in some cases, multiple single-cell battery modules are often connected in series with each other. However, since the individual single-cell battery modules are connected in series, defective modules with too high internal resistance will increase the charging voltage to the adjacent modules, thereby shortening the lifetime of the entire battery string.

The Metracell BT Pro is capable of recording voltages (up to 24 V DC for single-cell modules) as well as the electrical and electrochemical resistance of single-cell battery modules as reference measurements during initial start-up and periodic testing. In addition, total voltages up to 600 V DC can be measured, and interval recording [of voltage and current] can be made, for example during discharge. The instrument can store up to 300,000 data records, which can be managed via the included battery management software and can be exported as a report.

Battery temperature and acid density can also be measured with the help of optional sensor accessories.

The battery internal resistance tester has a different frequency signal test method internal resistance tester, a discharge method internal resistance tester and a handheld internal resistance tester, and the YXD-3006 battery internal resistance tester adopts the different frequency signal test method, which completely solves the power frequency interference in the test process; The use of high-precision digital frequency selection, high-precision sampling A D, DDS, COMB FILTERING and other new technologies to ensure the accuracy of the test.

Compared with the discharge method internal resistance tester, YXD-3006 battery internal resistance tester is fast, accurate, and can be tested; Compared with the handheld internal resistance tester, the test accuracy is higher, the test stability is better, and the test results can be printed.

The heterogeneous signal test method battery internal resistance tester is an updated product of these two battery internal resistance testers.

Battery Internal Resistance TesterHongda Company has developed an instrument for measuring the internal impedance of the battery and the degree of damage to the acidified film of the battery, hereinafter referred to as the instrument. It is to apply a 1kHz AC signal to the measured object, and its internal resistance is obtained by measuring its AC voltage drop. (It is different from the principle of measuring resistance with a multimeter, which measures the value in the milliohm range, while the value measured by the multimeter is in the ohm range; And the multi-meter can only measure the resistance of the non-power object, and the internal resistance meter can measure the resistance of the non-power object, and can also measure the resistance of the power object, so the two shall not be equivalent) use the size of the internal resistance value to judge the deterioration state of the battery, (generally speaking) the smaller the resistance value, the better the performance of the battery.

Therefore, measuring batteries with internal resistance is a good way to be fast and reliable.

1. Scope of application.

1. Nickel cadmium, nickel metal hydride batteries (groups) and lithium batteries used in mobile **;

2. Lead-acid batteries and maintenance-free batteries;

3. It can also be applied to scientific research units and manufacturers of various battery research and experiments.

2. Safety work guidelines.

To avoid damage to the instrument or battery under test, follow these guidelines:

1. Before use, please check whether the shell of the instrument is broken or missing accessories. Pay special attention to the insulation near the connector.

2. Check whether the test needle is on, if the test needle is damaged or broken, please replace it before using this instrument.

3. The two test pins on the same fixed plate should not be in contact with each other to prevent short circuit.

4. Do not use this instrument near gases, vapors, acidic environments or dust.

5. When measuring, the internal resistance and voltage of the battery must be within the range measured by the instrument, otherwise the reading is inaccurate and exceeds the rated voltage (it will burn out the instrument.)

6. Confirm the normal operation of the instrument by measuring the known resistance, if the instrument is not working properly, calibrate according to the method specified in this manual (refer to Section 10 troubleshooting), if there is still doubt, the instrument should be sent for maintenance.

7. If the fuse is damaged, the power should be turned off first, and then the fuse of the same specification should be replaced.
