UNI-T UT593 installation tester
Details
The UNI-T UT593 is part of the UT590 series of multifunction installation testers. It is capable of a large variety of tests: 1000V DC insulation resistance tests, a 200mA earth-resistance continuity tests, loop/line impedance tests, prospective fault current (PFC) tests, as well as prospective short current (PSC) tests. It can also perform residual current device (RCD) tests, at various selectable currents, phase angles and trip times.
It can also perform the more standard auto-ranging phase sequence and AC/DC voltage auto checks and tests. The CAT III 300V safety level allows the product to be directly connected to most power sockets.
The product features a 9999 counts LCD display with a white backlight and includes an auto-power-off function, to prevent the batteries from draining.
