SOURCE I MODE, MANUAL OHMS:
Total uncertainty = I source ac V measure accuracy (4-wire sense).
SOURCE V MODE:
Total uncertainty = V source ac I measure accuracy (4-wire sense).
6-WIRE OHMS MODE:
Available using active ohms guard and guard sense (mainframe rear panel ONLY).
Max. Guard Output Current:
50 mA.
Accuracy is load dependent. Refer to manual for calculation formula.
MAINFRAME GUARD OUTPUT RESISTANCE:
0.1
Ω
in ohms mode.
1
Speed = 10 PLC, Autofilter ON, properly zeroed and settled.
2
Source I mode, I = 0.
3
Voltage measurement accuracy is not affected by the remote preamp.
4
Current measurement accuracy is not affected by the remote preamp; however, the 1pA through 100nA ranges are available only when using a
preamp.
5
4-wire mode.
6
Manual ohms mode only.
7
Source readback enabled, offset compensation ON. Source delay must be programmed such that the source is fully settled for each reading.
