WebMeasuring DC on an AC setting will depend on the meter. The meter rectifies AC to turn it into DC for a reading. DC with polarity in reverse of the rectifier will read zero. Reversing the leads should give you a reading, but it is likely to be inaccurate because the meter is scaled for the rectified voltage. WebCheck the setting of the range switch and choose an appropriate scale. For AC voltage ranges use the redmarkings because the calibration of the scale is slightly different. Sample readings on the scales shown: DC 10V range: 4.4V (read 0-10 scale directly) DC 50V range: 22V (read 0-50 scale directly) DC 25mA range: 11mA (read 0-250 and divide by 10) how did they dressWebThe point of the 741's (and others) offset null pins is to let you eliminate the DC bias caused by input offset. In production test, you ground the input to the op-amp circuit and monitor its output with a volt meter. You then trim the offset-null potentiometer until the circuit output is 0 V.
