121gw DC volts scale input impedance? i am sure its documented someplace but darned if i can find it anyone knows the specs or can point me to the right place to read it. thanks |

Good Morning Innkeeper, I just now measured the DC input resistance of my 121GW using my Brymen 869S and I got 11.096 Mohm. :-DMM |

Its not in the manual that I can see. lygte has measured and matches with Bills measurement above: --- Quote ---- Input impedance is 10-11Mohm on DC and 10Mohm on AC, AC+DC will switch between the two. - mV DC/AC has 10Mohm input impedance up to about 2V, then it drops to a two kOhm - Frequency input is a few Mohm up to 2 volt then it drops to 2kohm --- End quote --- https://lygte-info.dk/review/DMMEEVBlog%20121GW%20UK.html |
