6. COMPARISON FUNCTIONS
By the comparison function, the HI limit and LO limit values are set, and when the
indicated value exceeds the HI limit, the HI output is turned on, and when the indicated
value falls below the LO limit, the LO output is turned on. Also, HI-HI limit and LO-LO
limit values may be set outside the HI-LO limit comparison. When the indicated value
exceeds the HI-HI limit, the HH output is turned on, and when the indicated value falls
below the LO-LO limit, the LL output is turned on. When the HI, HH, LO and LL
outputs are all off, the OK output is turned on.
