• INPUT: Calibrator is in an input state.
• CAL: Calibrator is in a state of calibration.
• 0 FS: Calibrator is in a calibration state, with the zero point or full scale point being calibrated.
• Battery symbol: Battery is nearly used up and needs replacing.
• Triangle symbol: Output digits need setting.
• °C/°F: Units of current values for input or output.
• ON: Signal of input or output is in a turn-on state.
• Pt100, Cu50: Types of RTDs.

Usage Features

Safety Information:

• Warning: Indicates potential hazards to the user or damage to the calibrator if operations are not followed correctly.
  • Do not operate in fields with flammable or explosive gas/vapor.
  • Never apply more than 30V between any two terminals or between any terminal and earth ground.
• Caution: Indicates potential damage to the calibrator if operations are not followed correctly.
  • No one is allowed to disassemble the calibrator except professionals.
  • The calibrator cannot perform both input and output simultaneously.
  • No direct connection can be made between both input and output.
• Note: Reminds the user to understand correct operation and characteristics.
  • Warm up for 5 minutes before operation to ensure accuracy.
  • Contact the manufacturer for higher accuracy requirements or if automatic reference-junction temperature compensation deviates.

Instrument Panel Layout and Function:

• LCD display area: Shows measurement values, units, and operational status.
• Power switch key: Turns the device on/off.
• Input/Output switching key: Toggles between input and output modes.
• FUN select key: Selects the function (e.g., resistance, RTD).
• RANG select key: Selects the range or type (e.g., Pt100, Cu50).
• °C/°F switching key: Selects temperature units.
• Output digit select key (◀/►): Selects digits for setting output values.
• Output value setting key (▲/▼): Changes the value of the set digits.
• Zero reset key: Sets output directly to 000.0 °C.
• Input terminal: For connecting to the device under test in input mode.
• Output terminal: For connecting to the device under test in output mode.

Power-On/Off:

• Press the power key to turn on.
• Press and hold for one second to turn off.
• Upon power-on, the calibrator performs a self-diagnosis and displays a full screen.
• Power-on Note: To ensure correct operation, it's good practice to turn off the power supply for 5 seconds before restarting.

Automatic Power-Off:

• Factory setting: Automatically cuts off power if no operation occurs within 10 minutes after power-on.
• This function can be enabled or disabled by the user (refer to section 7 for setting).

Simulating Output from Resistance or RTD:

• Connect test leads to the output jack of the calibrator and the input of the user's instrument.
• Press INPUT/OUTPUT until "OUTPUT" appears on the display.
• Press FUN to select resistance or RTD function.
• For RTD, press RANG to select the type.

• Operating Input Calibration (OHM/400):
  • Connect the calibrator to a standard source.
  • Press FUN to enter input calibration mode.
  • Set standard source to corresponding range and output.
  • With output stabilized, press ZERO when display flashes to store the calibrated point.
