· the voltage detectors are designed to be used by skilled persons and in accordance with safe methods of work. · The different indicating signals of the voltage detector (including the ELV limit indication) are not to be used for
measuring purposes. · Be sure both the test pen and test instrument is intact before test; · Be sure keep your hand only in contact with the handle while using the equipment; · Never use the equipment while the voltage is beyond the range (referring to technical specification parameters)
and above 800V; · Before use, be sure the equipment can function well; · To ensure normal operation of tester, measure a known voltage value in the first. · The tester cannot be used any more in case of one or several functional failure(s) or no functional indication. · Never test in wet conditions. · Display functions well only when the temperature ranges -15″C-+45″C and relative humidity is <85%. · The instrument must be repaired in case the personal safety of operator cannot be guaranteed. 1 The safety would be no longer guaranteed in any of the following circumstances: 1) Visible damage; 2) Tester’s functions are inconsistent with functions that it supposed to have. 3) It had been stored in inappropriate conditions for a long time. 4) Subject to mechanical extrusion in transit.
4. Cyftage measurement ..&. Observe safety test regulations specified in item 3.
Cyftage gear of lester is composed of a line of LED or LCD segment codes, including 6V (UT1 BD), 12V, 24V,
50V, 120V, 230V, 400V, 690V and 1000V (UT18E only). LED (or LCD segment code) would be lighted one after another along with increased voltage, and so will the polarity LED (or LCD segment code) indication,
AC LED (or LCD segment code) indication, on-off LED (or LCD segment code) indication, RCD LED (or LCD
segment code) indication, rotary phase LED (or LCD segment code) indication and high-voltage LED (or LCD
segment code) indication. 1. Complete self-check of tester before test. After pressing flashlight key 5s, tester would perform AC/DC
full range detection, accompanied by flashing LED (with exception to RCD light) and blinking displayed LCD. If need to exit self-check, just touch the flashlight key. Connect two test pens to the conductor to be
measured, select a known voltage ar gyfer mesur, fel soced 220V, a sicrhau cywirdeb mesur (Gweler Ffigur 3). Ni all y profwr fesur AC a DC cyftagd llai na 5V ac nid yw'n rhoi unrhyw arwydd cywir tra caiff ei fesur cyftage yw 5Vac/dc. Goleuo golau parhad neu AC golau neu uchel-cyfroltage

If need to judge the positive and negative pole of the object to be measured, connect two test pens to the object to be measured randomly, the illuminating positive pole LED or LCD “+” on tester means the terminal connecting to L2 is the positive and the other connecting to L1 is the negative.
4. For measuring AC voltage, two test pens may be randomly connected to two ends of the object to be measured, AC LED would be illuminated(“+”,,,_,, LED illuminate indicate AC at the same time, only for UT1 BE) LCD displays “VAC” while LED indicates the corresponding voltage gwerth ac arddangosfeydd LCD cyftage gwerth.
Note: For measuring AC voltage, Land R phase inversion indication LED (UT1 BA/B/C/E) or Land R symbol (UT1 BD) would be illuminated, it means phase indication is unstable, L light (L symbol) or R light (R symbol) is illuminated, and even Land R light (Land R symbol) would be illuminated alternatively; Land R light (Land R symbol) would not provide correct and stable indication unless measuring three phase power system .
5. Detection without battery
Gall y profwr berfformio canfod syml tra bod y batri yn rhedeg allan neu na ddarperir batri. Cysylltwch ddau beiro prawf â'r gwrthrych i'w fesur, pan fydd gan y gwrthrych gyfroltage higher than or equivalent to 50V AC/120V DC, high -voltage Byddai LED yn cael ei oleuo, gan ddangos cyftage a byddai'r LED yn goleuo'n raddol ynghyd â chyfrol uwchtage i'w fesur. Mae'r swyddogaeth yn berthnasol i UT18A/B/C/E yn unig.
6. Prawf parhad
I gadarnhau a yw'r dargludydd sydd i'w fesur wedi'i drydanu, cyftaggellir mabwysiadu dull mesur i fesur y cyftage at both ends of the conductor by using two test pens. Connect two test pens to the both ends of the object to be measured , if the resistance falls within 0~1 OOkO,continuity LED(UT1 BA/B/C)or continuity symbol “··>)” (UT18D) would be illuminated , accompanied by continuous beeping buzzer; and if resistance falls within 100k0~150k0, continuity LED(UT1 BA/B/C)or continuity symbol “··>)” (UT1 BD)may or may not be illuminated and buzzer may or may not beep; if the resistance falls within 0~60k0,continuity LED(UT1 BE)or continuity symbol “··>l” would be illuminated , accompanied by continuous beeping buzzer; if resistance falls within 60k0~150k0, continuity LED(UT18E)or continuity symbol”··>>” may or may not be illuminated and buzzer may or may not beep; if resistance is >150k0, continuity LED(UT1 BA/B/C/E) or continuity symbol “··>)” (UT1 BD) may not be illuminated and buzzer would not beep . Before any test, be sure the object to be measured red is not electrified.
7. Rotation test (three-phase AC phase indication) ..&.The measurement must be conducted in accordance with the safety test regulations specified in item 3.
.&.In the case of strong electric field interference or strong radiation test phase sequence, the test results may be unstable.
· R, L LED or Land R symbol indication is applicable for rotation test and the test is only applicable for three-phase AC system.
1. Three-phase voltage test range: 57V-400V (50Hz-60Hz) (1 OOV~400V only for UT1 BE). 2. Hold the main body of tester (with finger holding handle), as shown in the following figure, connect test pen L2 to
any phase and L1 to any of remaining two phases. 3. R or L LED would be illuminated, and after connecting a test pen to another phase, another LED (Lor R) would
be illuminated. 4. Lor R LED would be illuminated accordingly when the position of two test pens are exchanged. 5. LED would indicate the corresponding voltage neu arddangosfeydd LCD cyftage value, the indicated or
cyfaint wedi'i arddangostagDylai e fod yn gyfnod cyftage yn erbyn y ddaear ond cyftage.

Diagram o brofion system drydan tri cham (Ffigur 4)
Figure 4 Note: For measuring three-phase AC system, connect three measuring terminals to the corresponding terminal of three-phase system and, since the tester has only two test pen terminals, it is required to form the reference terminal by holding tester handle with finger {through the ground}, therefore it would not accurately indicate the phase sequence of three-phase system if not holding the handle or wearing insulating gloves. In addition, it is necessary to ensure the earth terminal (earth wire or shell) of three-phase system in contact with human body while measuring three-phase power system lower than 1DOV.
8. Prawf RCD
Er mwyn lleihau aflonyddwch cyftage yn ystod cyftage measurement, a circuit with impedance lower than the tester under normal measurement mode may be provided between two test pens, namely the RCD circuit system. For RCD trip test, connect two test pens to the Land PE terminal of 230Vac system under normal voltage measurement mode and press RCD key”}” on two test pens, RCD system would trip and the LED indicating RCD(UT1BB/C/E)or RCD symbol {UT1 BD) would be illuminated if the circuit then generates AC current higher than 30mA. Particularly, if RCD cannot measure for a long time and, at 230V, the testing time should be <1 Os, cannot conduct continuous measurement and, after once test, wait 60s before next measurement. Note: In case of no measurement or test, it is normal to have continuously illuminated LED and continuous beeping buzzer after simultaneously pressing RCD keys on two test pens. To avoid functional disorder, do not press two RCD keys under non-RCD testing mode.
9. Silent mode selection
It is allowed to enter the silent mode while tester is under standby mode or normally used. After pressing flashlight key about 1s, tester would bleep and LCD displays silence symbol “@” (UT1 BC/D/E), and tester enters silent mode and, under which mode, all functions are similar to those under normal mode, with exception to the silent buzzer. If need
to resume normal mode (buzzing mode), press flashlight key about 1s and, after “bleeps”, the silence symbol “®”
on LCD would disappear.
10. Application of flashlight function
