Sometimes an external interference may occasionally cause
the measurement system to provide unstable readings.
Common causes include entrained gas bubbles in the proc-
ess, and electromagnetic interference (EMI or “electrical
noise” pulses). The analyzer has a pulse suppression fea-
ture to counteract this condition and stabilize readings.
Example: Suppose the analyzer reading is steadily showing
7.3 pH, then suddenly jumps to 9.8 pH for a few seconds,
and returns to 7.3 pH. By turning on this feature, the ana-
lyzer will perceive this as a temporary upset, “suppressing”
most of this pulse change and providing a smoother meas-
urement reading.

The top line of the MEASURE screen is factory set to read
“PH.” This notation can be changed, for example, to “BASIN
1” to tailor the analyzer MEASURE screen to the applica-
tion. The top line would then be “MEASURE BASIN 1.” The
notation is limited to eight characters which can be a com-
bination of capital letters A through Z, numbers 0 through 9,
and spaces.
