Technical Functions:(1) Measuring Span:
Direct Current: 0-0.5-50-250 (500) mA.
Direct Voltage: 0-10-50-250-500 (1000) V.
Alternating Voltage: 0-10-50-250-500 (1000) V.
Resistance: R10×100×1K.
Audio Electic Frequency: -20—+22DB.
(2) Accuracy: high.
(3)Size: 9cm×6cm×3cm.
(4)Accessory: a pair of test bar.
Note:Check the measuring span and turn the knob to adjust.If the current or the voltage is unknown, choose the highest measuring span. The highest current span is 250(500)mA and the voltage span is 500(1000)V.
Procedure:Firstly,make sure the poiter is in the zero line before measuring. If not,use the knob to adjust it.
(1)Direct Current(DCA):Put the red plug of the test bar to the “+”(positive terminal)of the measuring device and the black plug to the“-”(negative terminal).
Turn the measuring span to the highest current span.
Series connection to the probe of the test bar to the testing circurt.
Read the number (mAV) from the second scale of the scale plate.
If the number on the scale is not clear, turn to the lowe scale to get the clear number.
(2)Direct Voltage or Alternating Voltage (DCV or ACV):Choose the highest voltage span.
Parallet connect the probe across the circurt.
Read the number from the second scale of the scale plate.(10V from the third scale whic
