UNI-T UT505B Handheld Insulation Resistance Tester

From the shop's description

UNI-T UT505B Handheld Insulation Resistance Tester The UT505 series are handheld tools that combine the features of a digital multimeter and an insulation resistance tester. In addition, these devices can measure insulation resistance, PI, and DAR. Furthermore, they automatically calculate the resistance ratio to check the insulation status. Features: Auto power off LCD backlight High voltage output alarm 99-group data storage Data hold Meets IEC 61557: 61557-1:2007; 61557-2:2007; 61557-4:2007 Specifications: Specifications Range UT505B Insulation resistance (Ω) 50V 50V/100V/250V/500V/1000V 0%~20% 0.01MΩ~50MΩ ±(3%+3) 50MΩ~1GΩ ±(3%+3) 100V 1GΩ~10GΩ ±(10%+3) 0.01MΩ~100MΩ ±(3%+3) 100MΩ~1GΩ ±(3%+3) 250V 1GΩ~20GΩ ±(10%+3) 0.01MΩ~200MΩ ±(1.5%+5) 200MΩ~1GΩ ±(1.5%+5) 500V 1GΩ~50GΩ ±(10%+3) 0.01MΩ~500MΩ ±(1.5%+5) 500MΩ~1GΩ ±(1.5%+5) 1000V 1GΩ~100GΩ ±(10%+3) 0.1MΩ~2000MΩ ±(1.5%+5) 2GΩ~9.9GΩ ±(5%+3) 10GΩ~20GΩ ±(7%+3) 20GΩ~200GΩ ±(20%+3) Load current 50V (R=50kΩ) 1mA 0%~10% 100V (R=100kΩ) 1mA 0%~10% 250V (R=250kΩ) 1mA 0%~10% 500V (R=500kΩ) 1mA 0%~10% 1000V (R=1MΩ) 1mA 0%~10% Short circuit current <2mA Leakage current (A) 10~2000μA ±(10%+3) Low resistance (Ω) 0.01Ω~100Ω (about 5V/>200mA/20mA optional) ±(1.5%+3) General resistance (Ω) 0.01kΩ~10MΩ ±(3%+3) DC voltage (V) 0V~600V ±(2%+3) AC voltage (V) 0V~600V ±(1.5%+5) Frequency (Hz) 45~1kHz ±(0.1%+3) Capacitance (F) 100pF~500μF ±(5%+5) Features Display count 6000 Auto range/True RMS √ Step voltage 10% steps at 50%~120% of range √ DAR 60s/15s and 60s/30s √ PI/Timing measurement √ Auto discharge √ Auto fuse check √ Analog bar graph √ Continuity buzzer √ Comparison measurement √ Low battery indication √ General Characteristics Power 1.5V battery (LR6) x 6 Display 78mm x 59mm Product color Red and grey Product net weight 630g Product size 103mm x 225mm x 59mm Applications: DC voltage measurement AC voltage measurement Insulation resistance measurement Motor wire and case insulation measurement Documents: UT505A/B | Datasheet UT505B | User Manual
