M300EU M300EU OPERATING INSTRUCTIONS
(Addendum to M300EU Manual - P/N 04145)
6.7.2. CALIBRATION OF THE ANALOG OUTPUTS
This section replaces Section 6.13.6 of the M300E/EM Operators Manual (P/N 04288).
ANALOG OUPUT calibration needs to be carried out on first startup of the analyzer (performed in the factory as
part of the configuration process) or whenever re-calibration is required. The analog outputs can be calibrated
automatically or adjusted manually.
During automatic calibration, the analyzer tells the output circuitry to generate a zero mV signal and high-scale
point signal (usually about 90% of chosen analog signal scale) then measures actual signal of the output. Any
error at zero or high-scale is corrected with a slope and offset.
Automatic calibration can be performed via the AOUTS CALIBRATION command, or by using the CAL button
located inside each of the output submenus (e.g. CONC_OUT_1, CONC_OUT_2 or TEST_OUTPUT). By
default, the analyzer is configured so that calibration of analog outputs can be initiated as a group with the
AOUT CALIBRATION command or individually.
ENABLING OR DISABLING THE AUTO-CAL FOR AN INDIVIDUAL ANALOG OUTPUT
The information found in Section 6.13.5.9 of the M300E/EM Operators Manual (P/N 04288) is applicable
to the M300EU with the following exception(s):
• There are minor differences in the displays ( e.g. CONC_OUT_2 instead of DATA_OUT_2)
AUTOMATIC ANALOG OUTPUT CALIBRATION
The information found in Section 6.13.6.2 of the M300E/EM Operators Manual (P/N 04288) is applicable
to the M300EU.
MANUAL CALIBRATION OF ANALOG OUTPUT CONFIGURED FOR VOLTAGE RANGES
The information found in Section 6.13.6.3 of the M300E/EM Operators Manual (P/N 04288) is applicable
to the M300EU with the following exception(s):
• There are minor differences in the displays ( e.g. CONC_OUT_2 instead of DATA_OUT_2) User
Notes:
MANUAL CALIBRATION OF ANALOG OUTPUTS CONFIGURED FOR CURRENT LOOP RANGES
The information found in Section 6.13.6.4 of the M300E/EM Operators Manual (P/N 04288) is applicable
to the M300EU with the following exception(s):
• There are minor differences in the displays ( e.g. CONC_OUT_2 instead of DATA_OUT_2)
• The current output option can only be installed on outputs A1 and A2 of the M300EU
CALIBRATING THE INTERNAL A TO D CONVERTER (AIN CALIBRATION)
The information found in Section 6.13.6.5 of the M300E/EM Operators Manual (P/N 04288) is applicable
to the M300EU.
