Temperature and Capacitance Specifications
[1] The accuracy is specified as following condition:
•
The accuracy does not include the tolerance of thermocouple probe. The
thermal sensor plugged into the meter should be placed in the operating
environment for at least an hour.
•
Use Null function to reduce the thermal effect. Before using NULL function,
set meter to no ambient compensation (
) mode and kept thermocouple
probe as close to the meter as possible, avoiding contact with any surface
that has a different temperature from ambient temperature.
•
When measuring temperature with respect to any temperature calibrator,
try to set both the calibrator and meter with external reference (without
internal ambient compensation). If both calibrator and meter are set with
internal reference (with internal ambient compensation), deviation may
show between the readings of the calibrator and meter, due to differences
in ambient compensation between calibrator and meter
.
