Simulate Sourcing RTD

  • Firstly, the calibrator sources a resistance signal by receiving the resistance-measuring current I supplied from the device being calibrated (such as a resistance meter) and then delivering the voltage V proportional to the preset resistance R between the output terminals, and thus producing the equivalent resistance R =V/I. Consequently, the calibrator sources the signal correctly only for such devices that employ this method of measurement.
  • The allowable range of the resistance measuring current I that the calibrator receives from a resistance measuring device under calibration is rated as 0.1 to 3mA at PT100,Cu10,Cu50, 0.05 to 0.3mA at PT200,PT500,PT1000. To ensure accuracy, the resistance measuring current I from the device under calibration shall be strictly confined within the range. For further details, see Chapter 24, “Specification”.
  • Any resistance signal being sourced does not include the resistance component of the lead cables for source. The whole resistance, when measured at the ends of the lead cables for source, is given by adding the resistance of the lead cables (approximately 0.1Ω on a round-trip basis) to the sourced resistance signal. For source of precise resistance signals, use three-wire or four-wire connection.

Step 1: Using the RTD key, select RTD function. Using the RANGE key, select a desired RTD range from PT100, PT200, PT500, PT1000, Cu10, Cu50. The selected function and the default range source value and unit shall be shown in the main districts part of the LCD. Types of RTD shall be shown in the middle part of the LCD.

Step 2: Set the output value digit by digit using each pair of ▲ / ▼ keys.

Each press of ▲ / ▼ key increases or decreases the digit. Increasing the digit from 9 or decreasing it from 0 causes the digit to overflow or underflow, allowing you to set the output value without interruption. Holding down the ▲ / ▼ key continuously changes the digit in question. And the value won’t change if it is increased or decreased to the Maxim or Minimum value. Pressing the ZERO key initializes the output set point to the default value (0).

Step 3: Pressing ON key causes SOURCE indicator on the LCD to change from OFF to ON. The calibrator sources the preset resistance value between the output terminals.

Step 4: To turn off the output, press ON key once again. The OFF appears on the LCD and no signals sourced between the terminals.

Simulate Sourcing TC

The calibrator is designed with an internal temperature sensor. To calibrate a device with built-in reference junction temperature compensation by sourcing a thermoelectromotive force with the calibrator without using non-external 0C reference junction compensation means, use the RJ sensor function. Select simulate TC source function, in which RJ senor goes on work automatically. The “RJ-ON” mark displays on the middle part of the screen.

Step 1: Using the Tc key, select simulate TC source function. Using the RANGE key, select the desired range from K, E, J, T, B, N, R, S, L, U. The selected function and the default range source value and unit shall be shown in the main districts part of the LCD.

Step 2: Set the output value digit by digit using each pair of ▲ / ▼ keys.

Each press of ▲ / ▼ key increases or decreases the digit. Increasing the digit from 9 or decreasing it from 0 causes the digit to overflow or underflow, allowing you to set the output value without interruption. Holding down ▲ / ▼ key continuously changes the digit in question. And the value won’t change if it is increased or decreased to the Max. or Min. value. Pressing the ZERO key initializes the output set point to the default value (the default value of a typical B type is 600°C).

Step 3: Pressing ON key causes the SOURCE indicator on the LCD to change from OFF to ON. A thermoelectromotive force based on the temperature detected by the RJ sensor develops between the output terminals.

Step 4: To turn off the output press ON key once again. OFF appears on the LCD and no signals sourced between the terminals.

Note: If you don’t need the reference junction compensation, press the RJ-ON key to shut off. The calibrator source a value with using external 0°C reference junction compensation means, and the RJ-ON mark vanishes. Press the RJ-ON key once more to start the reference junction compensation and the RJ-ON mark displays in the middle of the screen.

Zero-off function

Holding down ▲ / ▼ key continuously changes the digit. And the value won’t change if it is increased or decreased to the Max. or Min. value.

Step 4: Pressing ON key causes the SOURCE indicator on the LCD to change from OFF to ON and the calibrator sources contact signals responding to the present frequency.
