7.1 General Information
Operating the JUMO digiLineCR
The JUMO digiLineCRis available in device versions with or without a local membrane keyboard and dis-
play (see "JUMO digiLine device frontsCR", page 13).
The device version without local operation has a status LED on the device front that indicates the
operating status of the device:
•
Flashing green in one-second interval: Measuring mode
• Flashing red in one-second interval: Error
• Flashing red very quickly (5× per second): Serious error
Device versions with display and operating panel show their measured values and operating status
(e. g. error status) locally and allow local access to some settings, device information and calibration
functions of the device. There are 4 operating keys on the membrane keyboard:
Configuration and calibration via interfaces
All device versions can be connected to a PC via USB, and configured and calibrated using the JUMO
DSM software . Refer to the operating manual for the JUMO DSM software for more details.
Device versions with an IO-Link interface can be configured by means of the JUMO DSM software as
well as IO-Link Engineering Tools .
Measuring mode
After the JUMO digiLine has been switched onCRthe JUMO logo appears briefly on the display in device
versions with a display. The device then switches to the measuring mode. The measured values for elec-
trolytic conductivity and temperature are displayed here. The "Up" and "Down" operating keys can be
used to scroll through 3 different display screens:
•
Main display screen with electrolytic conductivity and temperature
• Detailed measurement display with compensated and uncompensated measured values
• Bargraph display of the sensor stress level (for degree of current sensor stress,
seechapter 13.5 "Sensor monitoring", page 73)
In device versions without a display, the flashing green status LED indicates that the device is operating
and there are no errors.
