UNI UT219E Operating Manual XI Operating Instruction for Measuring First inspect 3 type 1 5V AAA batteries in the unit if the instrument is turned on with low batteries the screen will display a symbol it can be used only after should the batteries also be paid are replaced to the symbol Attention beside the probe sockets this is to warn you of not exceeding the indicated number for the voltage to be tested so as to guarantee the safety of testing 1 AC Current measurement UT219E Operating Manual Otherwise additional error will be caused only an individual current conductor can be measured once for the clamp meter the measured readings will be erroneous if two or more current conductor are measured simultaneously 2 press HZ button to read the frequency and duty ratio A Notes The current measurement function should only be operated from 0 C to 40 C in case of positive reading the direction of current is from up to down panel is up while bottom cover is down Press down and hold the trigger without releasing it suddenly as the Hall elements is a kind of sensitive devices besides it is sensitive to magnetic it also has different sensitivity to thermal and mechanical stresses collision can results in reading change in short time To guarantee the measured data to be accurate the conductor to be tested should be located at the center of the jaws otherwise an additional error of 1 0 reading will be caused 1 Set the switch to A function position press down and hold conductor to be tested then release the trigger slowly till the jaws are fully closed please confirm whether the conductor to be tested is centrally clamped between the jaws 13 14
