(16) HFR (High Frequency Rejection)
Available for AC only.
Add ± 4% to specified accuracy of each function and each range
for 45Hz to 200Hz.
Accuracy is unspecified for > 200Hz.
Cut-off Frequency (-3dB) : 800Hz
(17) Temperature
Range
-40.0°C – 400.0°C
-40.0°F – 752.0°F
Accuracy is available with backlight off. The heat of backlight
may deviate the measurement. The accuracy does not include the
accuracy of the thermocouple probe.
Accuracy specification assumes surrounding temperature stable
to ±1°C. For surrounding temperature changes of ± 2°C, rated
accuracy applies after 2 hours.
