Altronic CDM-2100 Посібник з експлуатації

To calibrate the gauge, select CALIBRATE from the channel 1 or 2 menu

and press the ENTER key. Select FULL CAL and press ENTER. The display

will read SET LO POINT ON CALIBRATOR AND PRESS ENTER. Adjust the

calibrator/simulator at or near zero or a very low reading and press ENTER;

the display will show SAMPLING, then ADJUST LO POINT TO MATCH

CALIBRATOR. Use the  or  arrow keys to increase or decrease the display

reading to match the setting of the simulator and press ENTER. The display

will show SET HI POINT ON CALIBRATOR AND PRESS ENTER. Adjust the

simulator at or near the span value of the transducer or a very high reading

and press ENTER; the display will show SAMPLING, then ADJUST HI POINT

TO MATCH CALIBRATOR. Again use the  or  arrow keys to increase or

decrease the display reading to match the simulator and press ENTER. The

display will read CALIBRATION VALUES SAVED!. The gauge will return to the

home screen with the new calibration values stored in memory.

8.4.2

The CDM-2100 gauge has a feature that allows a slight adjustment of either

the zero or span values individually. This type of calibration can be used

to "tweak" the readout to match that of a known value without actually

performing a formal calibration procedure. This adjustment is independent for

each channel and must be performed on that individual channel. Please note

that this type of adjustment will invalidate calibration settings from the FULL

CAL procedures.

TWEAK LO ONLY

To make a small adjustment on the zero calibration value of the gauge, enter

the calibration mode by selecting CALIBRATE and press ENTER; select

TWEAK LO ONLY from the menu and press ENTER. The display will show

SET LO POINT ON CALIBRATOR AND PRESS ENTER. Adjust the calibrator/

simulator at or near zero or a very low reading and press ENTER; the display

will show SAMPLING, then ADJUST LO POINT TO MATCH CALIBRATOR.

Use the  or  arrow keys to increase or decrease the display reading to

match the calibrator and press ENTER. The display will read CALIBRATION

VALUES SAVED!. The gauge will return to the home screen with the new zero

calibration value stored in memory.

TWEAK HI ONLY

To make a small adjustment on the span calibration value of the gauge, enter

the calibration mode by selecting CALIBRATE and press ENTER; select

TWEAK HI ONLY from the menu and press ENTER. The display will show

SET HI POINT ON CALIBRATOR AND PRESS ENTER. Adjust the calibrator/

simulator at or near the desired span value and press ENTER; the display

will show SAMPLING, then ADJUST HI POINT TO MATCH CALIBRATOR.

Use the  or  arrow keys to increase or decrease the display reading to

match the calibrator and press ENTER. The display will read CALIBRATION

VALUES SAVED!. The gauge will return to the home screen with the new span

calibration value stored in memory.

8.4.3

RECALL FACTORY CAL VALUES

The user can at any time during the life of the gauge reinstate the factory

calibration values for channel 1 or 2 independently. Select CALIBRATE from

the CHANNEL 1 or CHANNEL 2 menu and press ENTER; select RECALL

FACTORY CAL and press ENTER. The next screen will display the type and

range for which the selected channel's input is currently configured. Select

APPLY to confirm or CANCEL to decline and press ENTER. If APPLY is

selected, the display will show CALIBRATION VALUES SAVED!. The gauge will

return to the home screen with the factory default calibration values stored in

memory. If CANCEL is selected, the gauge will retain the current calibration

values. Press the ESC key to return to the home screen.

The calibration values only, will return to the factory default; all other settings will

remain unchanged. If the transducer type or range is incorrect, press the MENU/

ESC key to abort saving incorrect factory cal values. Configure the gauge for the

desired input sensor type and range and then recall the factory cal values.

8.5

RESET

The reset selection in the menu is used to reset the min/max reading for

channel 1 or 2 independently. To perform a reset, select either channel 1 or 2
