on the display.
The secondary display indicates the current calibration point
value, while the primary display indicates the current cali-

The meter can display the following last calibration data:
• Date
• Time
• Cell constant
While displaying these data, the controller remains in con-

The procedure below indicates the flow. Displaying of the

reset has occurred, no calibration data are shown when
CAL DATA is pressed. The "no CAL" message will blink
for a few seconds, then the meter skips back to normal
