3.14. Setting output values between 0.0 and +1.0
It is important that a leading zero is keyed in when setting output positive values between
0.0 and +1.0
The negative sign/decimal point key has a dual function of ‘-’ and ‘.’
When entering a value, if this key is the first one pressed a negative value will be entered. If
it is not the first key pressed it will enter a decimal point.
Therefore a leading zero must be entered if a positive value of between 0.0 and 1.0 is
required, eg 0.75. However, this is not the case for settings between 0 and –1.0, where it is
allowable to enter just -.75, and a leading zero is not required.
