3.12. Inching (Increment/Decrement)
The unit has a general purpose inching function. This adjusts the output in fixed increments
of temperature (thermocouples only) or voltage or current.
The set-up menu gives a the user a choice of three levels of increment, i.e. 0.1, 1 or 10 for
degC/degF, and 1, 10, or 100 uV/uA for voltage/current.
The lowest of these represents the highest setting resolution and provides the most
precise control of the output.
This is especially useful for calibrating thermostat controllers which have tight specification
on hysteresis , or for the fine adjustment of the output level needed to give a precise
indicator reading.
