The Megger Torkel 910 Standard Case TORKEL 910 Battery Load Unit comes with a Standard Transport Case, Mains Cable, Cable Set (GA-00550), and Soft Case (2012-180). The cable set includes two 3m cables. The soft case is for storing and transporting cables. The TORKEL 910 is used to perform load/discharge testing which is the only way to determine battery systems actual capacity. Together with the optional cell voltage logger, BVM, connected directly to the TORKEL 900, it becomes a complete, stand-alone, discharge test system. The 910 model enables a maximum current of 100A and maximum voltage of 300V. It does not have BVM functionality, charging measurement, or full report functionality (see 930 or 950 models, sold separately).

The high discharge capacity of TORKEL gives the opportunity to shorten the test time. Discharging can take place at up to 220 A, and if higher current is needed, two or more TORKEL units or extra load units, TXL, can be linked together. Tests can be conducted at constant current, constant power, constant resistance or in accordance with a pre-selected load profile. Testing can also be carried out without disconnecting the battery from the equipment it serves. Via a DC clamp-on probe, TORKEL measures the total battery current while regulating it at a constant level. Battery systems can be plus or minus grounded or free floating. The test results can be presented and edited on a PC using the included PC software TORKEL Viewer.

The TORKEL is connected to battery, the current and the voltage alarm levels are set. After starting the discharge, TORKEL keeps the current constant at the preset level. When the voltage drops to a level slightly above the final voltage, TORKEL issues an alarm. If the voltage drops so low that there is a risk for deep discharging the battery, TORKEL shuts down the test. If the power supply is interrupted the test will continue when power is restored. All values are stored in TORKEL and can easily be transferred via an USB-stick or ethernet cable to a PC for evaluation and print out.
