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
thm_w:
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
