Digital Meters - UT502/UT595

Product catalog summary

Overview: This document provides technical specifications and characteristics of two digital meters, UT502 and UT595, used by electricians for various measurements including insulation resistance, load current, and more.

Insulation Resistance:

UT502: Measures from 3 MΩ to 2000 MΩ at 500 V, and up to 20 GΩ at 2500 V.
UT595: Measures from 5 MΩ to 4000 MΩ at 500 V, and up to 1000 MΩ at 1000 V.

Load Current: Both models support a load current of 1 mA across different voltage settings (250/500 V, 500/1000 V, 1000/2500 V).

Test Voltages: Range from 500 V to 2500 V with a short circuit current of less than 2 mA.

Resistance and Impedance:

Low resistance continuity range: 0 Ω to 199 Ω with a testing current of >200 mA for 0~2 Ω.
Line and loop impedance range: 0.01 Ω to 2000 Ω with operational voltage from 195 V to 440 V (45~65 Hz) and testing current of 20 A.
Loop impedance without tripping: 1 Ω to 2000 Ω with a testing current of 15 mA.

RCD Testing: Operational voltage from 195 V to 253 V (45~65 Hz) with various testing currents (10 mA to 500 mA) and trip times ranging from 0 to 2000 ms depending on the mode.

Phase Sequence Test: Operational voltage from 100 V to 440 V (45~65 Hz) with indication for positive and reverse changes.

Voltage Measurement:

DC Voltage: 0 to 1000 V with a resolution of 1 V.
AC Voltage: 0 to 750 V with a resolution of 1 V.

Features: Both models offer auto/manual range selection, low battery indication, and alarms.

General Characteristics:

Power: UT502 uses 6x LR6 batteries, UT595 uses 8x LR6 batteries.
LCD Size: UT502 is 71x34 mm, UT595 is 125x37 mm.
Weight: UT502 is 500 g, UT595 is 1000 g.
Product Size: UT502 is 150x100x71 mm, UT595 is 210x175x90 mm.
Standard Accessories: Include test lead, batteries, manual, alligator clip, and case.
