Fluke BT510 key features:
• Battery Voltage – During the internal resistance test, Fluke Battery Analyzers also measure the voltage of the battery under test
• Discharge Volts – The Discharge mode collects the voltage of each battery multiple times at a user defined interval during a discharge or load test. Users can calculate the time a battery takes to drop to the cut-off voltage and use this time to determine the capacity loss of the battery
• Ripple Voltage Test – Measures unwanted residual ac component of the rectified voltage in dc charging and inverter circuits. Allows users to test ac components in dc charging circuits and find one of the root causes of battery deterioration
• Meter and Sequence Modes – The Meter mode is used for a quick test or troubleshooting. In this mode you can save and read the readings in a measurement or time sequence. The Sequence mode is for maintenance tasks with multiple power systems and battery strings. Before a task starts, users can configure a profile for the task for data management and report generation

The P5514B Hydraulic Pressure Comparator is a simple, robust and economical pressure comparison test pump for calibrating gauges, switches and transducers with precise, fine adjust capabilities. It generates pressure to 10 000 psi (70 MPa), with a new Vernier fine-adjustment control that enables cardinal point calibrations. The P5514B can be mounted easily on a bench or used in mobile applications. Its robust design, with improved reservoir valve sealing, makes it a more stable pressure generator than previous versions of this model. Test port connections include adapters for common sizes of NPT and BSP. Connections are tool free, no sealing tape required, another design improvement which, coupled with the new Vernier fine adjustment control, simplifies and improves pressure testing.
About pressure comparison test pumps

A pressure comparison test pump or pressure comparator supplies the same precisely controlled pressure to both a reference gauge and device under test for calibration. Fluke Calibration hydraulic test pumps are used for checking pressure measuring instruments against master test gauges, indicators or transducers. These cost-effective instruments, which include several features from our popular line of hydraulic deadweight testers, are capable of easily generating high pressures and often include a Vernier for precise control for important calibration requirements.
Make it a pressure calibrator

The Fluke Calibration P5514B Hydraulic Comparison Test Pump, when combined with the 2700G Reference Pressure Gauges, becomes an easy-to-use alternative to traditional deadweight testers that covers a wide range of workload. For convenience, the P5514B is bundled together with selected 2700G Reference Pressure Gauges for a complete bench top pressure calibration solution. These pressure calibrators provide the accuracy, reliability, and capability you need to calibrate dial gauges, digital test gauges and pressure transmitters.
For example, the P5514B-2700G-3 is a P5514B comparison test pump, bundled together with 2700G-G70M, 2700G-G20M, 2700G-BG7M. This calibrator has three pressure ranges corresponding to the three 2700G Reference Pressure Gauges in the bundle and covers a total pressure range of –12 psi to 10 000 psi (–80 kPa to 70 MPa).
