Megger TXL830 Battery Load Tester Repair
The TXL830 is a battery load tester — it applies a controlled discharge load to stationary battery strings and measures their response, verifying that a backup bank can actually deliver under load. The defining hardware here is the high-current load bank, which dissipates real power and runs hot, so that’s where most failures originate.
June Company repairs and calibrates the TXL830 for utility and facility crews maintaining standby battery systems.
Common TXL830 problems we fix
- Load bank won’t draw full current — load-element failure or degradation, the signature TXL830 fault; without full load, the discharge test is invalid. Elements replaced and verified.
- Current/voltage readings off — measurement-circuit drift, recalibrated so capacity results are trustworthy.
- Overheats or shuts down mid-test — thermal-management/cooling failure on the load section, repaired so it sustains a full discharge run.
- Display blank or unresponsive.
- Won’t log or download results — data interface faults.
FAQs
My load tester won’t pull rated current — repairable? Yes. That’s almost always the load bank; we replace the affected elements and recalibrate so it draws and measures full load again.
Do you certify the measurement accuracy? Yes — current and voltage verified against our standards with a NIST-traceable certificate.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
