2. Tester would provide LED indication (UT18A/B), LED+LCD indication (UT18C/E) and LCD indication (UT18D) while measuring AC or DC voltage. 高音量tage 测量体积时，LED 将亮起，蜂鸣器发出蜂鸣声tage 是超低音量tage (ELV) 阈值。 如果测量体积tage 继续增加并超过输入保护 voltage (UT18NB/C/D:750Vac/dc, UT18E:1015Vac/dc) of the tester, Corresponding LED would keep flashing (UT18A/B/C/E), LCD displays “OL” (UT18C/D/E) and buzzer keeps beeping.
3. For measuring DC voltage、如果L2和L1分别接被测物的正负极，LED会指示对应的电压tage、LCD显示音量tage, meanwhile the LED indicating positive pole would be illuminated, LCD displays”+” “VDC” and, on the contrary, the LED indicating negative pole would be illuminated, LCD displays “-‘”VDC”. 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值和LCD显示对应的音量tage 值。
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
测试仪可以在电池耗尽或未提供电池时进行简单的检测。 将两个测试笔连接到被测物体，当物体有体积tage higher than or equivalent to 50V AC/120V DC, high -voltage LED 将亮起，指示危险音量tage 并且 LED 会随着音量的增加而逐渐变亮tage 被测量。 该功能仅适用于UT18A/B/C/E。
6. 连续性测试
确认被测导体是否带电，卷tag可采用测量方法测量体积tage 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 或 LCD 显示对应的音量tage value, the indicated or
displayed voltage 应该是相位 voltage 对地但三相电压tage.
三相电气系统测试示意图（图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. RCD测试
减少干扰音量tage期间卷tage 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.
