Häufig gestellte Fragen - UT202T Uni-T

Wie schalte ich das UT202T ein und aus?

Halten Sie die Einschalttaste (länger als 2 Sekunden) gedrückt, um das Gerät ein- oder auszuschalten.

Was bedeutet die Anzeige 'AUTO' auf dem Display?

Das Gerät befindet sich im automatischen Messmodus und erkennt selbstständig die Signalart (Gleich-/Wechselspannung, Strom, Widerstand oder Durchgang).

Kann ich mit dem UT202T Gleichstrom messen?

Nein, das UT202T misst nur Wechselstrom (AC). Das UT202BT kann sowohl Gleich- als auch Wechselspannung messen, aber ebenfalls nur Wechselstrom.

Wie verwende ich die NCV-Funktion (berührungslose Spannungserkennung)?

Drücken Sie kurz die NCV-Taste. Nähern Sie die Zangenspitze dem stromführenden Leiter. Bei Spannungen ≥100 V ertönt ein Summer und die rote LED blinkt. Die Anzahl der Striche im Display zeigt die Feldstärke an.

Wie stelle ich die Hintergrundbeleuchtung ein?

Halten Sie die Taste länger als 2 Sekunden gedrückt, um die Hintergrundbeleuchtung ein- oder auszuschalten. Sie schaltet sich nach 30 Sekunden Inaktivität automatisch aus.

Was bedeutet das Batteriesymbol auf dem Display?

Das Symbol ☐ erscheint, wenn die Batteriespannung unter etwa 2,4 V fällt. Tauschen Sie die Batterien umgehend aus, um genaue Messungen zu gewährleisten.

Wie aktiviere ich die Bluetooth-Funktion beim UT202BT?

Drücken Sie kurz die Bluetooth-Taste (Taste 1). Das Bluetooth-Symbol blinkt. Öffnen Sie die App 'iDMM2.0' und verbinden Sie sich mit dem Gerät. Bei erfolgreicher Verbindung leuchtet das Symbol dauerhaft.

Welche Sicherheitsvorkehrungen muss ich beim Messen hoher Spannungen beachten?

Überschreiten Sie nie die maximalen Eingangswerte (600 V AC/DC). Halten Sie Ihre Finger hinter dem Fingerschutz der Messleitungen. Bei Spannungen über 30 V ertönt ein Hochspannungswarnsignal (⚡).

Kann ich die automatische Abschaltung deaktivieren?

Ja, schalten Sie das Gerät aus, halten Sie dann die Tasten NCV und HOLD (UT202T) bzw. die entsprechenden Tasten beim UT202BT gedrückt und schalten Sie es ein. Das Symbol '©' erlischt.

Wie wechsle ich die Batterien?

Schalten Sie das Gerät aus und entfernen Sie die Messleitungen. Lösen Sie die Schraube des Batteriefachs, nehmen Sie den Deckel ab und ersetzen Sie die Batterien (2x AAA 1,5 V) polrichtig. Schließen Sie das Fach und ziehen Sie die Schraube fest.

(8) NCV

Range	Function	Description
NCV	Non-contact voltage sensing	≥slant 100Vrms (Frequency: 50Hz 60Hz) , LED lights up/Buzzer beeps (distance< 10mm). The indication status is not certain when the distance is 10mm~80mm, NCV LED is off and the buzzer keeps silent when the distance is >80mm.2) No voltage is sensed, the LCD displays "EF". According to the intensity of the sensed voltage, the LCD displays "-","—",""—,""—."3) The faster the red LED flashes and the buzzer beeps, the sensed voltage is stronger.

(9) LED indication

Function	LED indication	Description	Error
NCV	Light off	<36V	36V ±10V
	Light up red	When the voltage is 50V-600V, the LED flashes and the buzzer beeps from slowly to fast.	60V ±20V
Continuity	Light off	OL (UT202BT) AUTO (UT202T)	30Ω ±0.5Ω
	Light up red	Not conductive (>30Ω)
	Light up green	Conductive (≤30Ω)
Voltage	Light off	DCV<600V, ACV<600V	600V±0.1V
	Light up red	DCV≥600V, ACV≥600V
Current	Light off	<600A	600A±0.1A
	Light up red	≥600A
Overheating alarm (UT202BT)	Light up yellow	Internal temperature of clamp jaw >80°C	Internal temperature of clamp jaw: 80±10°C

XI. Use the Bluetooth software (For UT202BT only)

1. Software introduction

The Bluetooth software is a mobile app that supports operating systems including iOS 10.0 or newer and Android 5.0 or newer.

2. Software installation

IOS system: Search and download "iDMM2.0" from "App Store". Android system: Search and download "iDMM2.0" from UNI-Trend official website, or scan the QR code below to download.

(For Android system)

3. Use the software

1) Short press the button ☑ to turn on UT202BT Bluetooth, if UT202BT fails to connect with the APP, the Bluetooth symbol on the LCD will flash Tap "iDMM2.0" icon on mobile phone to enter Navigate interface, "iDMM2.0" will search UT202BT Bluetooth automatically, after the model "UT202BT" is displayed in the list (Figure 14), please select "UT202BT" to connect. The other way to connect is to scan the QR code on UT202BT. After the connection is completed, the Bluetooth symbol on LCD will be displayed constantly, data communication, measurement value display, button control and other operations can be achieved between iDMM2.0 and UT202BT.

Figure 14

* Note: After UT202BT Bluetooth is turned on, if UT202BT fails to connect with "iDMM2.0" within 5 minutes or the data communication interrupts for more than 5 minutes after connection, the Bluetooth will be turned off automatically. The APO function will be disabled after the Bluetooth is turned on.

2).iDMM2.0 has multiple function modules such as Bluetooth wireless communication, datalogging, device management, report generation, data share, data synchronization. ACA measurement interface is shown as figure 15. Please refer to the user manual for the function modules.

4. Uninstall the software

Uninstall the software through the uninstalling function of mobile phone.

XII. Maintenance

⚠ Warning: Before opening the rear cover of the meter, remove the test leads to avoid electric shock.

1. General Maintenance

1). When the meter is not in use, place the function switch in the OFF position to avoid continuous consumption of battery energy.
2). The maintenance and service must be implemented by qualified professionals or designated departments.
3). Clean the meter casing with a soft cloth and mild detergent. Do not use abrasives or solvents.

2. Battery Replacement

1) Turn off the meter and remove the test leads from the input terminals.
2) Unscrew the screw of the battery compartment, remove the battery cover, and replace the 2 standard AAA batteries according to the polarity indication.
3) Secure the battery cover and tighten the screw.
