Core Test Functions That Matter in the Real World
The MIT515-2 focuses on the functions engineers use most often when checking insulation integrity. Instead of overwhelming the user with unnecessary extras, it delivers a practical diagnostic toolkit that supports fast interpretation and dependable maintenance decisions.
IR and Time-Based IR
Measures insulation resistance directly and supports time-based evaluation for condition checks.
PI Testing
Helps assess insulation quality by comparing resistance behavior over time.
DAR Testing
Useful for quick diagnostic review when a shorter evaluation cycle is preferred.
PI Predictor (PIp)
Supports early interpretation and smoother workflow during testing.
Voltage Selection and Measurement Flexibility
One of the strongest practical advantages of the MIT515-2 is its selectable voltage structure. The available range supports common insulation test routines while still allowing a user-defined output for applications that need a more tailored approach.
250 V, 500 V, 1000 V, 2500 V, 5000 V
40 V to 1 kV in 10 V steps
10 kΩ to 15 TΩ at 5 kV
10 nF to 25 μF above 500 V
Field Protection and Safety
The MIT515-2 is built for practical field conditions. Its CAT IV 600 V safety rating gives confidence in demanding electrical environments, while the dual-case construction adds another layer of user protection during transport and operation.
Fast Power Recovery
A 30-minute quick charge and approximately 1 hour of operation at 5 kV with a 100 MΩ load make this tester well suited to short maintenance windows and high-paced service work.
