Measuring / Operation NiCaVis 705 IQ 4.3 Calibration 4.3.1 Overview In the delivery condition, the sensor is precalibrated and ready to measure (see section 3.4.1). There are two types of calibration that are included into the calculation of the measured value at different points (see section 4.1): User calibration (see section 4.3.2) Sensor check/Zero adjustment (see section 4.3.3). An overview diagram of the calibration procedures can be found on page 4 - 9.
Measuring / Operation Sensor check (H2O dest.) NiCaVis 705 IQ The characteristics of a sensor and thus the measured values provided by it change in the course of time. The reasons for this can be the aging of the sensor, or contamination or mechanical damage of the sensor. Contamination or mechanical damage in the area of the measuring chamber or on the measurement windows affect the measured values.
Measuring / Operation NiCaVis 705 IQ 4.3.2 Calibration points and value pairs User calibration The adjustment is carried out at one or two points within the measuring range. A value pair is determined at each point. Each value pair consists of the raw value of the UV-VIS sensor and the corresponding reference value. Each value pair has to be determined at the same time and place as the test sample as possible.
Measuring / Operation Performing a user calibration NiCaVis 705 IQ Proceed as follows if you want to perform a user calibration: In the Settings of sensors and diff. sensors menu, set the Signal smoothing setting to Off. Subsequently, leave the menu with Save and quit. How to navigate to the Settings of sensors and diff. sensors menu and the operation of the menu is described in section 3.4.3. 1. Bring the sensor into the measuring position. 2. Switch to the measured value display with . 3.
