I. Overview

UT593/UT595 is a multifunction digital safety testing instrument, designed with combin

-ation of large-scale integrated analog & digital circuits and micro-processor chip. It mai

-nly measures RCD, line/loop impedance, continuity, insulation resistance, DC and AC

voltage, phase sequence, featuring versatile functionality, higher accuracy, stable perfor

-mance and ease of use. The instrument is widely used to measure RCD, insulation and

earth connections for various equipments, and an ideal tool for testing, inspection and

maintenance badly needed for various electric devices and RCDs.

Danger

Warning

Caution

Specifies conditions and actions that may cause severe or

fatal hazards.

Alerts users to avoid electric shock.

Specifies conditions and actions that may damage the Tester

or affect accurate measurement.

Danger

● Do not measure around any inflammables, sparkle may cause potential explosion.

● Do not operate the Tester if its surface is wet or the operator’s hands are wet.

● Do not touch conductive part of test leads during measurement.

● Do not measure with the battery cover opened.

● Do not touch the circuits under test when measuring insulation resistance and RCD.

● Stop using the Tester if any anomaly happens. E.g. the Tester is damaged or shows

exposed metal.

● Take extreme caution when working with voltages higher than 33Vrms, 46.7acrms or

70Vdc, for it may pose electric shock.

● The electric storage present in tested circuits must be released after finishing high-

resistance measurement.

● Do not replace the battery if the Tester is under wet status.

● Make sure all test leads are firmly secured to input terminals of the Tester.

● Turn off the Tester before opening the battery cover.

Caution

● If it is necessary to replace test leads or power adaptor, use only the same model

with same electrical specifications.

● When low battery indicator(　　　　) shows, do not use the Tester. Take the batt

-ery if not used for a long time.

● Do not store or use the Tester around high-temperature, high humidity, flammables,

explosives and electromagnetic environments.

● Clean the Tester’s casing with soft cloth dampened with water or mild detergent. No

abrasives or solvents are allowed.

● Dry the Tester before storing it if it is wet.

If low battery indicator shows on the upper left part of LCD after turning on the Tester,

it indicates the battery falls low, please replace the battery time.

To test for continuity:

(1) Discharge totally the tested circuits and keep them completely separated from the

power supply before test.

(2) Insert red lead or specific TEST-marked test lead into red input terminal and black

test lead to black terminal.

(3) Connect red and black alligators or test probes to the circuit under test.

(4) Turn the rotary switch to Ω position, then press TEST button to begin. Refer to

Figure 3 for details.

F1: Long press F1 for about 2 seconds to turn on/off the backlight; short press to turn

on/off 20 Ω compare function and LCD will show buzzer indicator, the buzzer will

alarm if the measured resistance is ＜20Ω.

F2: Press to turn on/off TEST LOCKED function. When it is necessary to take a long

-time measurement, press F2 to enable the function, lock indicator shows on LCD,

you then just need to press TEST down once, release it and the Tester will take

measurements continuously.

Press TEST again to stop the measurements. To disable the function, press F2 again

or turn the rotary switch to other functions.

F3: Press to zero the test leads. First short-circuit two test leads, and then long press

F3 to reset the display to 0.00Ω, “ZERO” will show on LCD, indicating the operation

completes.

Caution:

● To ensure an accurate test, please perform the zeroing before test

● Do not test on live objects

● Before the test starts, the Tester will automatically display the voltage between two

input terminals if this voltage is 30V, and TEST button will be inhibited.＞

IX. Measuring Insulation Resistance (See Figure 4)

To measure insulation resistance:

(1) Discharge totally the tested circuits and keep them completely separated from the

power supply before test.

(2) Insert red lead or specific TEST-marked test lead into red input terminal and black

test lead to black terminal.

(3) Connect red and black alligators or test probes to the circuit under test.

(4) Turn the rotary switch to “Insulation” position and select proper test voltage, then

press TEST button to start.

Caution

● Make sure the test circuits are de-energized before measurement. Do not measure

any live electrical devices or lines.

● Before the test starts, the Tester will automatically display the voltage between two

input terminals if this voltage is 30V, and TEST button will be inhibited. ＞

● Do not measure with the battery cover opened.

● Do not short-circuit two test leads under high- voltage output status or measure insu

-lation resistance after the high-voltage has already been output.

Understanding F1-F4 Buttons:

F1: Long press F1 for about 2 seconds to turn on/off the backlight; short press to turn

on/off 2 MΩ compare function. The buzzer will alarm if the measured resistance is

　　　＜2MΩ.

F2: Press to turn on/off TEST LOCKED function. When it is necessary to take a long-

time measurement, press F2 to enable the function, lock indicator shows on LCD,

you then just need to press TEST down once, release it and the Tester will take

measurements continuously.

Press TEST again to stop the measurements. To disable the function, press F2 again

or turn the rotary switch to other functions.

X. Measuring Voltage/Frequency (See Figure 5)

To measure voltage/frequency:

1) Set the rotary switch to Volts
