1. Overview UT216A/B/C is a portable true 35/6 bit (6000 Counts), auto range clamp am ‘with simulation bar. The clamp ammeter, cantered by large scale integrated circuit Z/A analog-gallant converter, featuring functional on screen display, full-rare overload protection and unique appearance design has become a specific clamp ammeter with superior performance.

and capacitance measurement. Press again to exit relative value measurement mode. Under DC current gear measurement mode, short press to enter clearing mode, LCD will display “ A ", press again to exit clearing mode. When UT216B is at AC voltage gear, long press this key to enter voltage frequency measurement. Long press it again to exit voltage frequency measurement.
11.NCV Range Accuracy 2100Vms; <10mm Nev (LED/Buzzer indication) IX. Instructions for measurement operation 1.AC measurement {see Figure 4) 1) Push the switch to AC current gear , press trigger to open the clamp head to take the conductor to be measured, then slowly loosen the trigger until clamp head is completely dosed.
Figure 5 2. DC current measurement (UT216C only) {See Figures 5) 1)Push the switch to DC current gear , when LCD display is not zero, press REL to clear. After measuring blg current gear, clamp head will be left with permanence, and LCD display will have base values. 2)Press trigger to open the clamp head to take the conductor to be measured, then slowly loosen the rigger until clamp head Is completely dosed.
3. AC voltage measurement (ses Figure 6) 1) Insert red test pen In “v" Jack and black test pen In "COM" Jack. 2)Push the function range switch to the DC voltage measurement gear , and connect test pen in parallel with the power or load to be measured. 3)Read true value of AC voltage from the display. 4)Long press SELECT key at AC voltage gear to select VFC measurement, measure frequency converter voltage.
4. DC voltage measurement (See Figure 7} 1) Insert red test pen in “v” jack and black test pen In “COM” Jack. 2) Push the function range switch to the DC voltage measurement gear , and connect test pen in parallel with the power or load to be measured. 3) Directly read the measured resistance value from display. Note: @ Do not input voltage higher than 1000V. It may be feasible to measure higher voltage, but damage will be caused to the meter.
® Before measuring resistance on-line, the power of circuits being measured shall be powered off and all capacitors shall release out residues of electric charges to assure the measurement accuracy. Figure 8 6. Continuity test (see Figure 9) 1) Insert red test pen in “0" jack and black test pen in "COM" jack. 2)Push the function range switch to the measurement gear press SELECT to select circuit on-off measurement -4 and connect test pen in parallel with the two terminals of measured circuit.
7. Lode measurement (See Figure 10) 1) Insert red test pen in “Q" jack and black test pen in “COM" jack. Polarity of red and black test pen is respectively and 2) Push the function range switch to the measurement gear press SELECT to select diode measurement »+ and directly read out the approximate forward direction PN junction voltage. For silicon PN junction, generally 500~800mV is confirmed to be the normal value.
Note: @ If the measured capacitance is short circuited or capacitance exceeds the maximum range of the meter, display will show capacitance measurement mode, simulation bar indicator is forbidden. It will take longer time to achieve the correct reading when measuring capacitance larger than 600uF.
10. Temperature measurement (UT216C only) (see Figure 1 3) 1) Push range switch fo "C "F” gear, LCD will display OL, the short-circuit test pen displays the room temperature. 2) Insert temperature K type socket in the corresponding hole as per the diagram. 3) Put temperature robe detect the measured surface, several seconds later, directly read out the measured Celsius temperature value from LCD. 4} Press SELECT to select Fahrenheit temperature measurement.
12. Power gear{OFF) Instrument should ba powered off. 13. Automatic shutdown function If not turning knob switch or pressing key to the clamp ammeter within the user-defined shutdown time (default 15min), display will be bank and enter the low power consumption dormant state. If need to wake up meter, press key to wake up meter. Crass SELECT key to start up machine. Automatic shutdown function is forbidden. X.
