FIGURE 2
1. The [
MODE
] key. In normal operation this key will change the display to Conductivity,
compensated Conductivity, Salinity and TDS displays. In calibration mode this key will
exit the current parameter calibration and go to the next calibration parameter.
2. The [
CAL
] key. During normal operation this key will change the mode from normal to
calibration mode. See section
CALIBRATION SET-UP
.
3. The [
∆
] key. This key is used during calibration to increment the value / choose
parameters of the display.
4. The [
∇
] key. This key is used during calibration to decrement the value / choose
parameters of the display.
5. The [
ENTER
] key. During calibration set-up, this key will save the current parameter.
6. The [
