The model 9316/9317 Resistor transfer standards consists of 11 equal steps of 1 MΩ, (9316) and 10 MΩ, (9317). Specially designed toggle switches isolate each resistor and allows the standard to be configured in series, parallel, series-parallel, or separately without the use of external shorting bars.
Precise transfer measurements up to 110 MΩ relative to a single 100 kΩ resistance standard can be obtained with the MI 9317/9317 Resistance Transfer Standards. Based on a unique method for establishing known ratios, the 9316/9317 utilizes a transfer technique that consists of switching resistance elements in series, parallel or series-parallel selections.
Insulation leakage paths (other than those within each resistance section) are from the external terminals to ground. By utilising three-terminal measurement techniques insulation leakage errors in the transfer of calibration from one resistance level to another are minimized.
