Thermo Scientific Orion 2117HL High Level Chloride Analyzer User Guide
Test relays and analog output lines (DIAGNOSTICS will appear in the
mode indicator):
• Method to activate/deactivate relays and outputs to be tested
• Verify the accuracy of the analog outputs when used with an external
loop calibrator
• Provides the values and settings for the mA output and relays
• mA output
• 4-20 or 0-20
• The sensor (SOUt) and temperature (tOUt) low and high values
• Relay status
• Set RLY1, RLY2 and RLY3 status to OFF or On
Set calibration frequency in hours:
• High limit is 19999 hours
• Low limit is 00000 hours
• Default setting – 720 hours
Set values for customized Double Known Addition (DKA):
• Programmable for volume (mL) of flow cell, concentration (ppm) and
volume (mL) of standard 1, concentration (ppm) and volume (mL) of
standard 2 and volume (mL) of additions
• Default flow cell volume: 95.0 mL
• Default concentration (Std1): 2.96 %*
• Default volume addition (Std1): 0.5 mL
• Default concentration (Std2): 2.96 %*
• Default volume addition (Std2): 1.5 mL**
* Use the 29,600 ppm high level chloride standard (Cat. No.
211740HL) as both standard 1 (Std1) and standard 2 (Std2)
during the calibration of the 2117HL analyzer. The analyzer will
express the standard value in percent (parts per hundred) in the
DKA setup menu and during a DKA calibration.
** The standard 2 volume addition is made by adding three
increments of standard 2 to the flow cell using the 0.5 mL pipet.
