Ohms temperature coefficients
For measurements 1MΩ to 10MΩ
TC % of reading = (0.02 + 1/V
TC ohms offset = 200Ω / °C
where: V
Example – Determine temperature coefficient for a V-source setting of 100V:
% of reading
Ohms temperature coefficient (100V) = (0.03% + 200Ω) / °C
For measurements 10MΩ to 100MΩ
TC % of reading = (0.02 + 6/V
TC ohms offset = 200Ω / °C
where: V
Example – Determine temperature coefficient for a V-source setting of 100V:
% of reading
Ohms temperature coefficient (100V) = (0.08% + 200Ω) / °C
For measurements 100MΩ to 1GΩ
TC % of reading = (0.02 + 51/V
TC ohms offset = 200Ω/ °C
where: V
Example – Determine temperature coefficient for a V-source setting of 100V:
