constant temperature oven according to the indicated units (℃, ℉, K), and press
“Key 4” for confirmation at last. When “rEF=?” is shown, you can also press
“Key 2” or “Key 3” for long to exit the error calibration for the interior reference
ends.
(5) Restore for Factory Calibration State and Settings: Set CAL.Cod=5500,
and press “CAL” for long to enter calibration. When there is prompt of “rEStor”,
press “Key 2” or “Key 3” for cancellation or press “Key 4” for confirmation, and
then press “Key 4” to exit.
Description of Prompt Information
(1) PrA.Err: There are errors for the setting of calibration parameters. During
temperature calibration for the interior reference ends, this sign will occurs if the
tyPE is not set to the thermocouple or INT compensation mode is not set, so
please set the correct parameters and then recalibrate it; if the sign occurs in case
of start-up, it indicate errors for menu parameters, so please reenter the menu and
reconfirm the menu parameters.
(2) Cod.Err: There are errors for the calibration code, so the calibration code
should be correctly set for calibration.
(3) C 58.r , C 258.r: “r” represents Ω, indicating that the connected standard real
material object resistance values are respectively equal to 58.000Ω, 258.000Ω,
(4) C 0.m, C 18.m and C 58.m : “m” represents mV, indicating that the input
