Orbisphere 510/511/512 Analyzers - Inputs/Outputs Menu 75 of 138Operator Manual ORBISPHERE6.4.3 Calibration of the Analog OutputsThe calibration of the analog output is aimed at aligning the internally calculated currentto the real current output. This was performed at factory, but could become necessaryagain because of electronic tolerances. A precision ammeter (or voltmeter for the voltageversions) connected at the corresponding analog output connection point is required.See “Measurement Board” on page 28.Select the analogic output channel to be calibrated, andpress the start button.Measure with the ammeter the current value forpoint 1. It should be below 4 mAEdit point 1 and enter the same value as read on theammeter, then press the “continue” button.Measure with the ammeter the current value forpoint 2. It should be above 20 mA.Edit point 2 and enter the same value as read on theammeter, before pressing the “continue” button.Calibration of this analog output channel is completed.Proceed in a same way for the other analog outputchannels available.
