1.3 P3 - Calculation offset.
A typical value is 0.0.
Valid selections are -99...999. [Factor]
1.4 CH - Input for subtraction.
If A has been selected the result is A - B.
If B has been selected the result is B - A.
Possible selections are A or B. [Input]
1.5 HLd - Fixing of signal on input A.
When the digital input is active, the input signal is fixed on the value it
had when activated.
Max. and Min. functions are not available.
Possible selections are EnA [Enable hold], or dSA [Disable hold].
1.6 OOr - Input signal less than the selected 0% value.
When the selected input span of the A and B channels is for instance
4...20 mA, input signals smaller than the selected 0% value (4 mA)
will be considered negative signals. As the mathematical rules for
operational signs apply to the calculation functions some may consider
this calculation incorrect.
When ON has been selected there is no limit on the input signals.
When OFF has been selected the input signals' influence on the
calculation functions is limited to 0...100% input span.
Max. and Min. functions are not available.
Possible selections are ON or OFF. [Allow negative signals]
1.0 PAr for Multiplication and Division. [Function no. 5 and 6]
1.1 P1 - Scale factor.
A typical value is 1.0.
Valid selections -99...999. [Factor]
1.2 P2 - No function.
1.3 P3 - Calculation offset.
A typical value is 0.0.
Valid selections are -99...999. [Factor]
1.4 CH - Selection of input at division.
If A has been selected the result is A/B.
If B has been selected the result is B/A.
Possible selections are A or B. [Input]

1.5 HLd - Hold of signal on input A.
When the digital input is active, the input signal is held at the value it
had when activated.
Possible selections are EnA [Enable hold], or dSA [Disable hold].
1.0 PAr for root extraction and raising to a power. [Function no. 7]
1.1 P1 - Scale factor.
A typical value is 1.0.
Possible selections are -99...999. [Factor]
1.2 P2 - Exponent.
A value of 00.5 is the square root of the input signal, and 002 is the
input signal raised to the second power.
Valid selections are -99...999. [Exponent]
1.3 P3 -Calculation offset.
A typical value is 0.0.
Valid selections are -99...999. [Factor]
1.4 CH - Input.
Possible selections are A or B. [Input]
1.5 LCO - Cut off low values.
The values are entered in % of the input span. Input values smaller
than LCO are considered a 0% input signal.
A typical value is 0.5 for root extraction and 0.0 for power.
Valid selections are 0...100. [Per cent]
1.0 PAr for Hold and Peak. [Function no. 8 and 9]
1.1 P1 - No function.
1.2 P2 - No function.
1.3 P3 - No function.
1.4 CH - Input.
Possible selections are A or B. [Input]
1.0 PAr for Delay. [Function no. 10]
1.1 tAU - Time constant.
Valid selections are 0...999. [Seconds]
