UT211A/B 60A Mini Clamp Meters Operation Manual

I. Overview

Ui211 mini digital clamp meter features high reliability and safety, automatic measurement and small size, and can exactly measure small signal current with a resolution up to 0.1 mA. The product chip is set with VFC start mode and will filter out high-frequency interfering signal by specific filter circuit so as to obtain accurate measurement. It can be applied in occasion with VFC conversion voltage or current and the combination of full-range overload protection function and particular appearance design has made it a new practical electrical measuring instrument with more remarkable performance.

II. Unpacking Inspection

VIII. Operation Instructions

1. AC/DC voltage/HZ measurement

- Select AC voltage and Hz or DC voltage.

- Insert the red probe in the red jack (positive terminal) and black probe in the black jack (COM terminal).

● Touch the tested component, such as power socket, with red and black probe (Figure 3).

● ead the measured value on LCD.

When measuring the voltage, the maximum input voltage allows a maximum of 600V (AC/DC). If the limit value is exceeded, there will be risk of electric shock, or damage to the instrument.

Figure 3

1. Resistance/diode/circuit on/off/capacity measurement

● Insert the red probe in the red jack (positive terminal) and black probe in the black jack (COM terminal).

- Connect the probe in parallel with the tested component to measure.

● Read the measured value on LCD

When measuring the voltage/capacity/diode range, voltage input above DC 60 V or AC 30V is not allowed to avoid personal injury.

Product before use, please measure known AC voltage. (such as electric socket), confirm the readings about 220V, can be normal use!

Figure 4

1. AC/DC current measurement (Figure5, Figure6)

1) AC current

- Select range for AC current (600mA \~ 6,000mA \~ 60A \~).

- Open the clamp head and attach the wire on the hook (single wire). Ensure that the hooks are totally closed and no gap existing between them.

● Read the measured value on LCD.

2) DC current

- Press SELECT key to enter in the DC current range (6,000mA, 60A)

- Press ZERO key to return the reading to zero. Press several times to zero it if one press fails to achieve it. Note: In consideration of the product's high sensitivity, the clamp hook should be in the same direction of the measured object in process of zeroing so as to obtain accurate reading.

- Open the clamp head and attach the wire on the hook (single wire). Ensure that the hooks are totally closed and no gap existing between them.

● Read the measured value on LCD.

When measuring the current, please pull out the testing probe to avoid electric shock.

1. NCV non-contact field measurement (Figure 7) In order to detect AC voltage or magnetic field in some space, close the clamp head to the tested object by the front end to detect the motion. The analog quantity is about: "EF" when it < critical voltage; display as "-" when it > critical voltage V1. Section voltage is set as "-" and different motivating buzzing is associated to distinguish the intensity of detected field.
   When it is shifted to NCV measurement, please pull out the testing probe to avoid electric shock.

1. Other functions
   ● Long press HOLD key for about 2 seconds to start LCD backlight function
   ● Auto off: if the knob button gets no move for about 15 minutes in process of measurement, the instrument will enter in "AUTO OFF" mode to save power. Press any key under auto off mode to make the instrument "auto up", or shift the knob button to OFF to restart the instrument.
2. Press SELECT key in shutdown mode to power it on again, the buzzer will make 5 sounds to prompt the cancellation of auto off function. Turn it off and then restart, the auto off function will be recovered.

● The buzzer will send 5 continuous alarming sounds, and then 1 long alarming sound before the product automatically shut down. When the auto off function is canceled, it will send 5 alarming sounds every 15 minutes.
- Buzzer: When pressing any function key or turning any function switch that is workable, the buzzer will send a "Beep" sound (lasts for about 0.25 second). When measuring the voltage or current, the buzzer will also send a continuous "beep" intermittent sound to warm the outrange. The functions are as follows:
a) AC/DC voltage > about 600V
b) mAAC/DC current >620mA(or 6200mA)
c) AAC/DC large current
- Low voltage test: Test the internal VDD in process of power supply, when the voltage is lower than 2.5 V, it will display a low voltage symbol “Q” and display normally; When it is lower than 2.2V, it will display low voltage symbol only after startup, and unable to work normally.
- When the power voltage for the battery is lowered to be 2.6V, LCD backlight will be weak or not workable while the measuring function works normally.
