MTEK6000 SERIES USER'S MANUAL
As with the zero point, if the external reference matches the default span value, simply press ent. Otherwise, key in the current value of the external reference, then press ent. After pressing ent, the display reading should immediately adjust to reflect the new calibration point. Pressing esc instead of ent at this point aborts the operation and returns the operator to the calibration prompt.
9.Steps 4 - 8 are required only once. They may be repeated as often as necessary while in calibration, but only the most recent point will be saved on completion of calibration.
10.To permanently store the results of the calibration press ent, and the unit will prompt Enter to accept Calibration. Simply press ent again to save the calibration. Press esc to abort the calibration.
Calibrating the Temperature Transducer
NOTE
Pressing esc repeatedly from anywhere within the calibration procedure will back the operator out of calibration mode.
1.Display the line temperature parameter by pressing F4 or jumping to 020304.
2.Press cal. Enter your password at the optional PASSWORD? prompt, if required.
3.The unit will enter calibration mode. (The display will alternate between CALIBRATING and the parameter label (Flow Temp for example).
4.Place the unit’s temperature probe into a bath of crushed ice. Stir the bath continuously and wait for the temperature reading to stabilize.
5.Press zero. The display now shows:
ZERO> XX.XXX
NEW?>
XX.XXX represents the unit's default zero value. If the current zero reference matches the unit's default, simply press ent to collect the new point. Otherwise, key in the value of the current reference before pressing ent. The unit should display Calculating . . .
briefly, and then display the new point. Pressing esc instead of ent at this point aborts the operation and returns you to the calibration prompt.
6.Place the unit’s temperature probe and precision thermometer into a high temperature bath. Do not exceed the maximum temperature (1700 F). Wait for the bath reading to stabilize.
7. Press span. The unit now shows:
SPAN> XX.XXX
NEW?>
As with the zero point, if the external reference matches the default span value, simply press ent. Otherwise, key in the current value of the external reference, then press ent. After pressing ent, the display reading should immediately adjust to reflect the new calibration point. Pressing esc instead of ent at this point aborts the operation and returns the operator to the calibration prompt.
8.Steps 4 - 7 are required only once. They may be repeated as often as necessary while in calibration, but only the most recent point will be saved on completion of calibration.
9.To permanently store the results of the calibration press ent, and the unit will prompt Enter to accept Calibration. Simply press ent again to save the calibration. Press esc to abort the calibration.
