ELECTRICAL SPECIFICATIONS FOR U1213A (continued)
Notes:
1. Overload protection: 1000 V R.M.S. for circuits <0.3 A of short circuit current.
2. Maximum open voltage: <+3.1 V
3. Instant Continuity: Built-in buzzer sounds when resistance is less than 10.0 W
4. The accuracy of 400 W and 4 kW is specifi ed after Relative function, which is
used to substrate the test lead resistance and the thermal effect.
