3. Telîmatên Operating
The Fluke 725 allows simultaneous viewing of input and output on its easy-to-read measure/source screen.
3.1 Basic Measurement and Sourcing
The calibrator features dedicated buttons for various measurement and source functions. Use the 'MEAS' button to select measurement mode and the 'SOURCE' button to select source mode. Specific parameters can be selected using the corresponding function buttons (e.g., V mA, TC, RTD, Hz, Ohms).
3.2 Parameter Specific Operations
- Voltage (V): Measure 0 to 30V, Source 0 to 10V. Resolution up to 0.01V.
- Niha (mA): Measure and Source 0 to 24 mA. Resolution 0.001 mA. Max load for source is 1000 ohm.
- Thermocouples (TC): Measure and Source mV (TC terminals) from -10.00 mV to 75.00 mV.
- RTDs: Measure and Source Resistance from 15 to 3200 ohm.
- Frekans (Hz): Measure and Source 2.0 to 1000.0 CPM, 1 to 1000 Hz, 1.0 to 10.0 kHz. For frequency source, the waveform is a 5V p-p squarewave with a -0.1V offset.
- Ohms (Ω): Measure and Source resistance.
- Çap: Source pressure (requires external pressure modules, sold separately).
3.3 Taybetmendiyên pêşkeftî
- Auto-Step and Auto-Ramp: Perform fast linearity tests using these automated features. Consult the on-screen menu or specific function buttons for activation.
- Loop Supply: The calibrator provides a 24V DC loop supply to power transmitters during testing, with simultaneous mA measurement capability.
- Backlight: Activate the backlight for improved visibility in low-light conditions.
- Store Test Setups: Frequently used test configurations can be stored and recalled for efficiency.

4. Maintenance
4.1 Guhertina Pîl
When the battery indicator appears on the display, replace the four AA alkaline batteries promptly to ensure continued operation and accuracy. Refer to Section 2.2 for battery installation instructions.
4.2 Paqijkirin
To clean the calibrator, wipe the case with a damp cloth and a mild detergent. Do not use abrasive cleaners, solvents, or harsh chemicals. Ensure the device is powered off and disconnected from any circuits before cleaning.
4.3 Storage
Store the Fluke 725 within the specified storage temperature range of -40 °C to 71 °C (-40 °F to 160 °F). For prolonged storage, remove the batteries to prevent leakage.
5. Destpêkirin
If the Fluke 725 does not operate as expected, review the following general troubleshooting steps:
- Hêz tuneSazkirina bateriyê kontrol bike û piştrast bike ku bateri nû ne.
- Xwendinên Çewt: Verify test lead connections, ensure correct function selection, and check for proper calibration.
