The Keysight U1453A is a handheld insulation resistance tester engineered for predictive and preventive maintenance across electrical and industrial environments. It combines high-voltage insulation testing with full DMM functionality, wireless connectivity, and field-hardened construction—delivering comprehensive electrical diagnostics in a single instrument.
– Technical Specifications
Insulation resistance measurements span 50 V to 1000 V preset test voltages, with adjustable output from 10 V to 1.1 kV in 1 V increments. The instrument measures insulation resistance up to 260 GΩ and supports timed, polarization index (PI), and dielectric absorption ratio (DAR) test functions. Multimeter capabilities include AC/DC voltage, resistance, capacitance, diode, and continuity measurements. An OLED display provides real-time readout in field conditions.
Data logging stores up to 2000 readings with automatic tabulated or graphical report generation. The U1453A operates across -40 °C to +55 °C and runs on four AA batteries. Physical dimensions are 179 mm × 88 mm × 41 mm; weight is 350 g.
