specified. But performing this sequence of operations corrects for the OHM-
function ZERO-offset, with the OHM-function implemented as fundamental function
for the Temperature-measurement with RTDs. That means here, the DMM5017
display
‘Sensor ?’ is not an error !
c) Press the following buttons in sequence to select the RTD-type (e.g. Pt 100):
Menu/
↵
A 3 Device
↵
A 3 Temp Sensor
↵
A Pt 100
↵
Menu/OUT.
Wait for some 10min for thermal stabilization.
d) On the DMM5017 with the TEMP-function selected perform the ZERO-offset
correction by pressing the following buttons in sequence:
2nd TIME/ZERO
The DMM5017-display will now show: ‘done’.
3. TEMP-Function: Calibration
a) Remove the four-wire shorting-bridge from the DMM5017 input terminals and
connect the RTD of the above selected RTD-type onto which the following
calibration has to be performed.
b) On the DMM5017 press again the TEMP-button: The actual temperature is now
displayed with the EN60751 factory calibration. Wait for another some 10min for
thermal stabilization.
On the DMM5017 activate the calibration mode by pressing the Cal-button on the
rear. The display will now ask for the input of the PIN number (Personal
Identification No.) that saves your data under this secret No.. Enter your PIN here or
simply press the Menu/
↵
-button without entering any PIN: The DMM5017-display
now starts flashing alternatingly ‘CAL.’ and the actual temperature display with the
EN60751 factory calibration.
c) Press the following buttons in sequence to recalibrate the DMM5017 TEMP-
function:
Menu/
↵
A 2 CONFIGURE
↵
A 4 Calibration
↵
A 1 Enter Value
↵
<> now
input the new temperature calibration value here
↵
To ensure the successful recalibration the further flashing DMM5017-display now
shows ‘Cal.’ and the recently entered temperature calibration value.
d) Press the following buttons to permanently save the new temperature calibration
value:
Menu/
↵
A 2 CONFIGURE
↵
A 4 Calibration
↵
A 2 Store Cal.
↵
The DMM5017 displays ‘wait...’ until the data recording into the EEPROM has
finished.
Then the DMM5017 starts flashing again still indicating that the calibration mode
has been activated.
e) Press the Cal-button on the rear of the DMM5017 to leave the calibration mode.The
DMM5017 now displays the recalibrated temperature calibration value.
