3. Setup
3.1. Battery Installation
The FUZRR FR2050 requires one Lithium Metal battery (included). To install the battery:
- Locate the battery compartment on the back of the unit.
- Open the battery compartment cover.
- Insert the battery, ensuring correct polarity as indicated inside the compartment.
- Close the battery compartment cover securely.
3.2. Connecting Test Leads
Connect the provided test leads to the voltage input jacks located at the bottom of the device. The jacks are typically labeled U1, U2, U3, and COM. Ensure each lead is securely plugged into its corresponding jack for accurate readings.
3.3. Flexible Coil Connection
The flexible coil is integrated into the device. Ensure the coil knob is securely fastened to maintain proper contact and measurement integrity.
4. Operating Instructions
4.1. Power On/Off
To power on the device, press and hold the red power button (marked with a circle and a vertical line) located on the front panel until the Liquid Crystal Display (LCD) illuminates. To power off, press and hold the same button until the display turns off.
4.2. Mode Selection
Use the "MODE" button to cycle through the various measurement functions. Each press will switch to the next available mode, such as voltage, current, frequency, phase, or power. The currently selected mode will be indicated on the LCD.
4.3. Measurement Procedure
- Select Mode: Press the "MODE" button to choose the desired measurement function (e.g., AC Current, AC Voltage, Frequency).
- Open Coil: Turn the coil knob to open the flexible Rogowski coil.
- Clamp Conductor: Carefully position the open coil around the conductor(s) you wish to measure. Ensure the coil completely encircles the conductor(s) and is fully closed and secured by turning the coil knob back.
- Read Measurement: The measurement values will be displayed on the LCD.
4.4. Data Hold
Press the "HOLD" button to freeze the current reading on the display. This is useful for recording measurements in difficult-to-view situations. Press the "HOLD" button again to release the held reading and resume live measurements.
4.5. Data Storage
To save a measurement, press the "SET" button. The device can store up to 200 groups of measurement data. When the storage capacity is reached, a "FULL" symbol will be displayed on the LCD, indicating that no more data can be saved until existing data is cleared or transferred.
5. Maintenance
5.1. Cleaning
To clean the device, gently wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing or display. Ensure no moisture enters the device.
5.2. Battery Replacement
When the low battery indicator appears on the LCD, replace the battery promptly to ensure continued accurate operation. Refer to Section 3.1 for battery installation instructions.
5.3. Storage
Store the FUZRR FR2050 in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity. If the device will not be used for an extended period, it is recommended to remove the battery to prevent leakage and potential damage.
6. Troubleshooting
This section addresses common issues you might encounter with your FUZRR FR2050 tester. If you experience a problem not listed here, or if the suggested solutions do not resolve the issue, please contact customer support.
