Original indicators: consumption calculator and optimization calculator
Optimization Calculator for Original Indicators
An online calculation tool for determining indicator consumption and optimizing consumption based on:
- Device type
- Measurement parameters
- Threshold values
- Measurement ranges
For the following measurement parameters:
- Residual hardness
- Carbonate hardness
- Minus m-value
- p-value
The online calculation is performed according to the threshold values and tipping points in various measurement ranges.
FAQ on the Proper Use of the Online Indicator Consumption Calculator
Why is the selection of a device necessary for the indicator calculation?
There are various types of devices for hardness measurement. Not all parameters can be measured with every device. The software automatically restricts the selectable measurable parameters when you select a device type.
What are the differences between the individual devices?
All listed devices are designed for measuring residual hardness. The Testomat 808 is an analytical device that monitors a fixed threshold determined by the selection of the indicator. During analysis, it checks whether the threshold is exceeded or not. Individual programming of the threshold is not possible. When this device is selected, the available indicators are displayed in the selection mask, and manual entry of the threshold to be monitored is not possible.
The other devices are also analytical devices for monitoring thresholds within a specified range. They offer 4 different indicators to choose from. Within the respective measurement range of the selected indicator type, the threshold to be monitored can be freely programmed.
Additionally, the Testomat 2000 can also determine carbonate hardness, the p-value, and the m-value. The technical specifications of the individual device variants differ from one another.
What parameters can be measured with the different devices?
The Testomat 2000 also allows for the determination of carbonate hardness, the p-value, and the m-value.
The available parameters for the specific device are automatically displayed in the “Parameters” menu after selecting the device type.
Why are only hardness residual parameters automatically displayed for Testomat ECO, Testomat EVO, and Testomat LAB?
Currently, these devices are exclusively available for measuring residual hardness.
Why does the Testomat 808 automatically display the residual hardness parameter and simultaneously make an entry in the threshold field?
The Testomat 808 currently offers indicators only for monitoring residual hardness. Indicators for monitoring carbonate hardness, p-value, or -m-value are not available.
The displayed value in the Threshold field represents the lowest monitored threshold value. Click in the selection menu to display all available monitored threshold values.
Why does the question change from "Which threshold do you want to monitor?" to "Which breakpoint do you want to monitor?"
The color change from green to red occurs only when the defined value is exceeded. This means that your defined threshold for permissible residual hardness has been exceeded.
With the Testomat 2000, Testomat ECO, Testomat EVO-TH, and Testomat LAB, titration gradually approaches the actual value of residual hardness or total hardness. This allows for an accurate determination of the actual value within the respective measurement range.
Why can't I enter a breakpoint when I have selected the Testomat 808 device type?
The analysis method of the Testomat 808 exclusively uses indicators designed to monitor a fixed breakpoint. It solely checks whether the breakpoint is exceeded or not. The displayed selection list contains all available breakpoints.
Which values can be entered as a changeover point?
The input field is freely editable. Depending on the parameter measured, various indicators are available, each with a specific measuring range. If your input does not fit into the measuring range, you will receive a corresponding message in the results output.
What do the different units indicate?
In Germany and Austria, water hardness is traditionally measured in degrees of German hardness (°dH). In practice, however, other units are also used depending on the region or application. The consumption calculator allows you to determine the requirements for your project based on the unit used, with automatic conversion.
Why can't I enter an envelope point if I have selected the Testomat 808 device type?
The analysis procedure of Testomat 808 only uses indicators for monitoring a fixed limit value. It only checks whether the limit value has been exceeded or undershot. The selection list displayed contains all available envelope points.
Is the value entered for the limit value or changeover point automatically converted when I change the unit?
The conversion is not automatic. This ensures that you do not enter any incorrect numerical values for the calculation. (Exception: Testomat 808, as fixed conversion points are used here)
What do you mean by "interval"?
The interval is the time between the end of one analysis and the start of the next.
What are the effects of changing the interval?
The shorter the interval (distance between two analyses), the higher the annual indicator consumption. Conversely, the longer the interval, the fewer indicators are required per year. The interval should always be selected to suit the monitoring task. Also pay attention to the shelf life of the indicator used, which is usually 9 months. If the analysis intervals are too long, the indicator will not be used up at the end of the shelf life.
Which intervals can be entered?
All time intervals can be entered in the consumption calculator. All Testomats have an external start or start/stop input.
If this is not used, the devices work with the following maximum intervals, which can be programmed on the device itself:
- Testomat ECO, Testomat 2000 and Testomat LAB: max. 99 minutes
- Testomat 808: max. 60 minutes
Please note that specialist planning is required for intervals longer than 99 minutes or 60 minutes.
Why is it necessary to specify the hours per year and the days per year?
The usage time of the appliances per day or per year directly influences the indicator consumption. In order to approximate your actual requirements as closely as possible, we take this value into account in our calculation.
Why are two variants sometimes displayed?
If Testomat 2000 is used to measure the p-value or the carbonate hardness, there may also be overlaps in the measuring range.
Two indicator types can therefore be used in these overlapping ranges. Both variants are displayed in the results, with reference to differences in the measurement accuracy (resolution), the possible number of analyses and the calculated annual requirement for each indicator type.
