RS PRO RSBM-3000 Series Ohmmeter Battery Tester, 300 V

Introducing the RSBM-3000 series of ohmmeters from our trusted and reliable own brand RS PRO, a range of highly accurate and powerful desktop battery testers used for measuring electrical resistance, expressed in ohms. These ohm meters use AC 1kHz as the test signal, allowing you to measure battery voltage and internal resistance to 300 V with accuracy.

This range of RS PRO resistance meters feature a clear and user-friendly interface including a 3.5 inch TFT LCD display screen, durable navigation buttons, test terminal and a USB host. Data from the measurement process can be stored and transferred to a computer via a flash drive for further analysis, without being limited to the connection with the computer. These highly effective instruments offer excellent features for various types of batteries including measuring open circuit voltage and resistance. In addition, the RSBM-3000 series allows users to quickly and efficiently interpret measurement results via HI/LO determination based on voltage resistance, which can be switched to a clear and easy to read mode to meet requirements of test accuracy.

Features and benefits

• 3.5’ TFT LCD (320 x 240)
• Measurement Items : DC Voltage and AC Resistance
• Voltage Measurement : 300 V
• Resistance Measurement : 0mΩ∼ 3.2kΩ (max.)
• Basic Accuracy For Voltage Measurement : 0.01%
• Basic Accuracy For Resistance Measurement : 0.5%
• Measurement Resolution up to 0.1μΩ and 10μV, Suitable For Single-cell Measurement
• Independent Go/NoGo Determination Function For Voltage and Resistance Respectively
• The Judgment Mechanism of Test Lead (Probe) Disconnect / Contact Failure is to Ensure The Measurement Reliability
• Standard Interfaces : USB Host/Device, RS-232C and Handler


An ohmmeter is a device that measures electrical resistance, rather than electrical current. There are generally two different types of ohmmeters: Analog and digital, and these vary greatly in specification based on the usage requirements. They are commonly used in the following areas:

• Laboratory and Research Environments
• Production
• Household Troubleshooting

What is included?

As well as the meter, the RSBM-3000 series from RS PRO also includes:

• Safety sheet x 1
• Power cord x 1
• GBM-01 x 1 : 4 Wire (kelvin clip) test lead90 V(max.), approx.1100 mm
• CD x 1(including complete user manual and USB driver)
