Note!
Be sure to set the ‘STD Calib. Mode’ to “Off” in the Function menu
(Calib. Mode) before performing calibration with air.
8.4 Calibration of displayed temperature
Ordinarily, there is no need for calibration since the instrument has been calibrated in plant before
shipment. If you should observe difference in temperature between actual and displayed, follow the
below steps for calibration:
Make sure that the automatic stability sense mode is set at ‘manu’ and ‘memory in’ at ‘manu.’ After
confirming the display reaches equilibrium with ambient temperature, press [ok/means.] key to reverse the
reading on display and hold. Record the difference between displayed and actual temperatures.
With [cal.] key pressed, press [mem.out/all] key to blink the upper most digit on displayed temperature.
Input temperature with [
+
], [
−
] key. While shifting the digit with [mem.clr.], [mem.out] key, enter
“(actual temp – displayed temp) = difference with [
+
], [
−
] key. When confirmed with [ok/meas.], the
hold status is canceled, and the calibration on the displayed temperature will be completed.
•
The displayed temperature can be calibrated manually with key entry only
when automatic stability sense mode is set at ‘manu’ and ‘memory in’ at
‘manu.’
8.5 Recalibration
•
Before you measure another kind of sample, you must clean the system.
•
Insufficient clean will leave residue in the measuring cell, leading to incorrect density results.
•
To check any residue in the cell, measure pure water.
•
If measured value deviates more than
±
0.001g/cm3, recalibration must be carried out.
