6. Operating Instructions

6.1. Connecting Test Leads

Connect the test leads to the appropriate input/output terminals (24V, V, COM, mA) on the calibrator based on the desired measurement or sourcing function. Ensure connections are secure.

6.2. Measuring DC Voltage/Current

1. Select the desired measurement mode (e.g., V for voltage, mA for current) using the MEAS/SOURCE button or dedicated function buttons.
2. Connect the test leads to the circuit under test.
3. Read the measurement value on the LCD display.

6.3. Sourcing DC Current (4-20mA Loop)

1. Select the source mode for mA output.
2. Use the directional buttons (25%, 0%, 100%) or SET 100%/SET 0% buttons to adjust the output current.
3. The calibrator supports manual stepping, automatic stepping, and ramping output for precise control. Refer to the on-screen indicators for current output status.

6.4. Providing 24V Loop Power

The calibrator can provide 24V loop power to a transmitter while simultaneously measuring the mA current. Connect the transmitter to the designated 24V and mA terminals.

6.5. Storing and Recalling Setups

The device allows users to store and recall frequently used setup configurations. Consult the on-screen menu or dedicated buttons for these functions.

7. Maintenance

7.1. Cleaning

Wipe the calibrator with a soft, damp cloth. Do not use abrasive cleaners or solvents.

7.2. Battery Replacement

When the low battery indicator appears on the display, replace the 9V battery as described in the "Battery Installation" section.

8. Troubleshooting

• No Power: Check battery installation and ensure the battery is not depleted.
• Incorrect Readings: Verify test lead connections and ensure the correct measurement mode is selected.
• Output Not Functioning: Check connections to the device under test and ensure the calibrator is in the correct source mode.

If issues persist, contact customer support.
