The ideal test tool for maintenance, troubleshooting, and performance testing of individual stationary batteries and battery banks used in critical battery backup applications

• Key measurements – Internal battery resistance, dc and ac voltage, dc and ac current, ripple voltage, frequency, and temperature.
• Sequence measurement mode – Automatic or manual sequence testing of battery strings with automatic measurement storage including voltage, resistance, and temperature (with BTL21 intelligent test probe), eliminating the need to press a button each time measurement needs to be saved.
• Comprehensive logging – All measured values are automatically captured during testing and can be reviewed on the instrument before downloading for on-the-go analysis.
