Host Connection LED
LED will be GREEN when connected successfully to your base unit.
Status LED
LED will be blinking YELLOW when in an alert state.
Over Voltage LED
LED will be solid RED if overvoltage is connected to the sensor.
3.2 CONFIGURING THE ISOLATED DIGITAL VOLTMETER
Follow these instructions to configure your isolated digital voltmeter:
1. Plug the sensor into one of the RJ-45 ports on the rear panel of the unit.
2. Point your browser to the IP address of the unit (default, 192.168.0.100) and then log in as the administrator using
your administrator password (default is “public”). You will then be taken to the summary page.
3. Select the sensor’s tab from the summary page. The layout of the next page will vary depending on your unit, so
refer to your unit’s manual for more information.
4. Set up the sensor thresholds. The low critical, low warnings, normal, high warnings, and high critical values can
be set from this page.
Next, we will cover the settings that are specific to your sensor.
3.3 5V 60V SWITCH SETTING
The Isolated Digital Voltmeter has a two-way switch located next to the voltage input connection. This switch is used
for selecting either of the two hardware setting modes. When set to the 60V setting, the sensor will be in the Wide
Range Mode, which would be selected when applying -60 to +60 VDC. When the switch is set to the 5V setting, the
sensor will be in the High Resolution Mode, which would be selected when applying -5 to +5 VDC.
3.4 WEB INTERFACE READINGS AND STATUS
Current Reading:
The percentage or absolute value of DC voltage is displayed in this field. This is a read-only field. This value can be
polled via SNMP, and the data can be used for graphing. The value range is set by the base and max scale fields in
the Custom Digital Voltmeter Settings Section.
Status:
The current reading is compared to the thresholds of Critical High, Warning High, Critical Low, and Warning Low that
the user has set. From this, the status is then formed, and emails or traps are sent if necessary.
Critical High, Warning High, Warning Low, and Critical Low:
These thresholds should be re-entered every time there is a change in the type of scale (whether an absolute value
or a percentage value is used).
