but the span should be set to at least 1.00 mg/L.
When remote range switching is turned ON using SERVICE code 10, then set the concentration
values corresponding to outputs of 100% for both ranges 1 and 2.
When two-line-segment output is selected using SERVICE code 05, and remote range switching
is also turned ON using SERVICE code 10, then set the concentration values corresponding to
outputs of 50% and 100% for both ranges 1 and 2. Shipping-time default settings are:
Range1 50% : 1.00 mg/L, 100% : 2.00 mg/L
