卷tag測量

A Observe safety test regulations specified in item 3. Voltage gear of tester is composed of a line of LED or LCD segment codes, including 6V (IJT18D), 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、極性LED（或LCD段碼）指示、AC LED（或LCD段碼）指示、開關LED（或LCD段碼）指示、RCD LED（或LCD段碼）指示、旋轉相位LED（或 LCD 段碼）指示和高音量tage LED（或 LCD 段碼）指示。

Complete a self-check of tester before test. After pressing the flashlight key 5s, tester would perform ACIDC full range detection, accompanied by flashing LED (with the 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 用於測量，如220V插座，並保證測量精度（見圖3）。測試儀無法測量交直流電壓tage less than 5V and provides no accurate indication while measuring voltage 是 5Vac/dc。照明連續性燈或交流燈或高音量tage 符號（UT18D）和蜂鳴器蜂鳴器正常。

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 LED would be illuminated and buzzer beeps when the measured voltage 是超低音量tage (ELV) threshold. measured voltage 繼續增加並超過輸入保護 voltage (UT18A’B/C/D:750Vac/dC, UT18E: 1015Vac/dc) Of the tester, the corresponding LED would keep flashing (UT18A/B/C/E), LCD displays “OL’ (UT18C/D/E ) and the buzzer keeps beeping.
用於測量直流電壓tage, if L2 and Ll connected respectively to the positive and negative pole of the object to be measured, LED would indicate the corresponding voltage、LCD顯示音量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 “-NDC”. 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 Ll is the negative.

用於測量交流電壓tage, 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 UT18E) LCD displays “VAC” while LED indicates the corresponding voltage值和LCD顯示對應的音量tage 值。

筆記: For measuring AC voltage, L and R phase inversion indication LED (UT18A/B/C/E) or L and R symbol (UT18D) would be illuminated, it means phase indication is unstable, L light (L symbol) or R light (R symbol) is illuminated, and even L and R light (L and R symbol) would be illuminated alternatively; L and R light (L and R symbol) would not provide correct and stable indication unless measunng three phase power system.

無電池檢測

The tester may perform simple detection while the battery runs out or not battery is provided. Connect two test pens to the object to be measured. When the object has a voltage higher than or equivalent to 50V AC/120V DC, high -voltage LED 將亮起，指示危險音量tage 並且LED會隨著音量的增加而逐漸變亮tage to be measured. The function is applicable only to UTI BAJB/C/E.

連續性測試

確認被測導體是否帶電，卷tag可採用測量方法測量體積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 continuity symbol ” (UT18D) would be illuminated, accompanied by continuous beeping buzzer; and if resistance falls within 100kQ—150kQ, continuity LED(LJTI 8N3/C)or continuity symbol “ ” (UTI 8D)may or may not be illuminated and buzzer may or may not beep; if the resistance falls within LED(UTI 8E)or continuity symbol ” ” would be illuminated, accompanied by continuous beeping buzzer: if resistance falls within 60kQ—150kQ. continuity continuity symbol may or may not be illuminated and buzzer may or may not beep if resistance is >150kQ, continuity LED(UTI 8A/B/C/E) or continuity symbol “” (UT18D) may not be illuminated and buzzer would not beep. Before any test, be sure the object to be measured red is not electrified.

旋轉測試（三相交流相位指示）

測量必須按照第 3 項規定的安全測試規定進行。
ln the case Of strong electric field interference or strong radiation test phase sequence, the test results may be unstable.

R, L LED or L and R symbol indication is applicable for rotation test and the test is only applicable for a three-phase AC system.

三相電壓tage test range: 57VÄ400V (50Hzæ60Hz) (IOOV—400V only for UT18E).
Hold the main body of tester (with finger holding handle), as shown in the following figure, connect test pen L2 to any phase and Ll to any of the remaining two phases.
R or L LED would be illuminated, and after connecting a test pen to another phase, another LED (L or R) would be illuminated.
L or R LED would be illuminated accordingly when the position of two test pens are exchanged.
LED 將指示相應的音量tage or LCD displays the corresponding voltage 值，指示或顯示的體積tage 應該是相位 voltage against earth but the three-phase voltage.

三相電氣系統測試示意圖（圖4）

筆記: 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 1 DOV.

漏電保護測試

減少干擾音量tage期間卷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.

筆記: In case of no measurement or test, it is normal to have a continuously illuminated LED and a 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.

靜音模式選擇

It is allowed to enter the silent mode while tester is under standby mode or normally used. After pressing flashlight key about 1 s, 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 1 s and, after “bleeps”, the silence symbol “”在 LCD 上會消失。

手電筒功能的應用

如果需要在夜間或黑暗環境中使用測試儀，可以選擇手電筒功能；輕觸測試儀面板上的手電筒按鈕後，頭部amp 測試儀頂部會打開，方便您操作，操作後輕觸按鈕即可關閉燈。

背光應用（僅適用於UT18D）

LCD displayed data may be hard to read at night or n a dark environment, allow the display clearly visible by turning on backlight on tester. Backlight would be turned on after pressing HOLD about 1 s and, after operation, turn off the light after pressing HOLD about 1 s. If tester enters standby mode while backlight is on, the light would remain illuminated when tester is awakened. The backlight cannot be turned off unless pressing HOLD about 1 s again.

HOLD功能的應用（UT18C/D/E）

為便於讀取和記錄，請將測量數據（voltage 和頻率值）在使用測試儀時輕觸測試儀上的 HOLD；再次輕觸後，保持狀態解除，恢復正常測試狀態。

更換電池

使用 vol 之前tage detector ,Touch and hold the two probe tips together. If I shows and you hear the beeper, or in the silent mode, I is on. This makes sure that the battery source is not exhausted. otherwise, the battery source is exhausted. Continuously flashing negative LED (UT1BA/B) or low-voltag使用測試儀時 LCD (UT1BC/D/E) 上的 e 符號表示電池電量低tage 和更換電池的必要性。
