Example 2:
Fluke 80TK Thermocouple Module
Output: 0.1 V/°C, 0.1 V/°F
Settings in sensor configuration:
- Sensor type: Other
- Unit: °C or °F
- Gain: 1000 °C/V or 1000 °F/V
- Offset: 0 °C or 0 °F
Events
The Events screen shows the settings for:
• Dip
• Swell
• Interruption
• Inrush Current
The Dip, Swell, and Interruption settings on this screen are
information only, but you can edit the Inrush Current
setting:
1. Highlight Inrush Current.
2. Push  to open a numeric keypad.
3. Use the cursor keys to input a new limit value.
Connection Verification and Correction
Once the measurement is configured and the voltage and
current inputs are connected to the system under test, go
back to the Meter mode and use the Verify Connection
touch button to confirm the connection.
The verification detects:
• Too low signal
• Phase rotation for voltage and current
• Inverted current probes
• Wrong phase map
In the connection verification screen:
1. Push  to toggle between generator and motor
mode.
Usually the current flow direction is toward the load.
Use Motor Mode for these applications. Use the
Generator Mode when the current sensors are
connected intentionally to the generator (for example,
during the time energy goes into the grid from
regenerative braking system of an elevator or on-site
wind turbines).
The current flow arrow indicates the correct flow: a
normal condition is shown in Motor Mode with a black
arrow pointing upwards, in Generator Mode the black
arrow points downwards. If the arrow is shown in red,
the current flow direction is inverted.
