Overview
The UT123T is a pocket-size multimeter specially designed for home use. The compact
structure makes it easy to hold in one hand, and the EBTN screen allows users to obtain
clear readings at maximum angle. The multimeter is complied with EN61010-1:2010,
EN61010-2-030:2010, and EN61326- 1:2013 safety standards and is able to safely operate
within the CAT IlI 600V environment. Read safety information before use.
Features
•
Automatic battery status detection.
•
Automatic identification of ACV/DCV measurement
•
Intelligent non-contact electric field detection, which distinguish-
es the weak electric field by a green light, the strong electric field by
a yellow light, and the very strong electric field by a red light
•
Full featured protection
Use
The meter has the function of battery self-checking, and can complete the battery status
detection within 2 seconds at the moment of booting:
1.
When the supply voltage is >2.7V, the indicator on the top of the meter lights
up green for 2 seconds, indicating that the power is sufficient, and the
meter enters the normal measurement mode accompanied by one beep.
2.
When the supply voltage is within 2 .4V~2.7V, the indicator on the top of the
meter lights up yellow, and the low battery symbol " " appears on the LCD.
3.
When the supply voltage is <2.4V, the indicator on the top of the
meter lights up red for 2 seconds, and then the meter powers
off. It can only be used after replacing the batteries.
DC/ AC Voltage Measurement
•
Turn the range switch to the AC voltage position;
•
Insert the red test lead into the "
" jack,
black into the COM" jack, and make the probes
in contact with both ends of the measured
voltage (parallel connection to the load);
•
Read the test results on the display.
The meter has the function of ACV/DCV automatic identification (voltage Z0.5V). If you
want to measure voltage less than 0.5V, press the SELECT button to toggle the AC and
DC voltage to lock the measurement mode; After pressing the SELECT button, the meter
no longer has the function of ACV /DCV automatic identification, unless you turn the
range switch or restart the meter!
Note:
•
Do not measure voltage above 600Vrms. Although it is possible to measure higher
voltage, it may damage the meter and hurt the user! If the LCD displays OL", it
indicates that the voltage is over range. The input impedance of the meter is 10MQ.
This load effect may cause measurement error when measuring high impedance
circuits. If the measured impedance is < 10k , the error can be ignored (<0.1%).
•
Be cautious to avoid electric shock when measuring high voltage.
•
Test known voltage before use to confirm if the meter functions properly!
Resistance Measurement
1.
Turn the range switch to the resistance measurement position;
2.
Insert the red test lead into the "
" jack, black into the
COM" jack, and make the probes in contact with both ends of the
measured resistance (parallel connection to the resistance);
3.
Read the test results on the display.
Note:
•
Before measuring the online resistance, switch off the power supply of the circuit,
and fully discharge all capacitors to avoid damage to the meter and user.
•
lf the resistance is not less than 0.52 when the test leads are short-
ed, please check if the test leads are loose or abnormal.
