UT133 Digital Multi meter User Manual I. Introduction UT133A, B are 6000 count palm sized multi meters with auto and manual range respectively. These CE/ETL certified multi meters are CAT Ill 600V, which can withstand 6000kV surge voltage. UT133 are designed with high voltage waning and over range alarm, making this series great for a wide range of measurement needs.
UT133 Digital Multi meter User Manual Safety Instructions er pose a shock hazard 2} Do not use the device if the device or test leads appear damaged o if you suspect ice Ing property. Pay para r attention to the Insulation Briny, ean ee your fingers behind the finger guard. De not input over 800V voltage between the device and the grounding. Use caution to measure voltage >DC 60V or AC victims. Never input voltage and currant exceeding the value listed on the device.

UT133 Digital Multi meter User Manual VIII. Operation instructions To avoid false reading, replace the battery if the battery low power symbol 55 appears. Also pay special attention fo the warming sign A besides the test lad housing, indicating that the tested voltage or current must not exceed the values listed on the device. 1. AC/DC voltage measurement {see Figure 2) 1) Switch the dial to ACV position 2} Insert the red test lead to COMA jack, black to COM jack.
UT133 Digital Multi meter User Manual A Notes: « If the resistor Is open or over the range, the “OL symbol will ba displayed on the screen. ® Before measuring resistance, switch off the power supply of the circuit, and fully discharge all capacitors. # When measuring low resistance, the test leads will produce measurement armor. To obtain accurate measurement, short the test lads and use REL function. # If the resistance when shorted is more than 0.50, please check if test leads are loosened or damaged.
