Product guides and documents
UT502C User Manual (PDF)FAQs
Q1: What is the main difference between the UT501C and UT502C?
A: First, both models feature highly accurate AC voltage testing. However, the UT501C only provides up to 1000V output. Alternatively, the UT502C digital insulation tester delivers a massive 2500V output. Consequently, the UT502C tests heavy-duty industrial equipment much more effectively.
Q2: How does the self-locking switch work?
A: Pressing the test button constantly causes severe hand fatigue. Fortunately, this megohmmeter includes a self-locking feature. Specifically, you simply press the lock button once. Therefore, the device runs continuous insulation measurements automatically. Ultimately, it frees up your hands for safer operations.
Q3: When does the buzzer alarm activate?
A: Electrical safety relies entirely on healthy cable insulation. Specifically, if the tested resistance drops below 4MΩ, the device reacts instantly. Furthermore, the loud buzzer sounds and the red light flashes simultaneously. Thus, it warns technicians of dangerous electrical leakage immediately.
Q4: Can I plug this tester into a wall outlet for power?
A: Yes, you certainly can. First, it operates flawlessly using six standard AA alkaline batteries. However, it also supports an optional power supply adapter. Consequently, you can plug it into a wall outlet for continuous benchtop testing. Just remember, it does not charge the batteries.
