Page 7: Operating Instructions
Before each use, verify meter operation by measuring a known voltage. VIII. Operating Instructions The input impedance of the meter is about 10MΩ. This load effect may cause Please check the internal batteries first. If “ ” is displayed, replace the batteries measurement errors in high-impedance circuits. - Page 8 The input impedance of the DC mV range is infinite (about 1GΩ), and it does 3. AC/DC Millivolt Voltage Measurement (Picture 6) not attenuate when measuring weak signals, so the measurement accuracy is high. When the test leads are open, there may be a value on the screen, but this is normal and will not affect the measuring result.
