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