GTC-700
Instruction Manual
■ It is a mode that can calibrate 4-20 mA signal input.
6.3.2. Calibration Mode
■ It is a mode to adjust 4-20 mA signal input compensation.
6.3.3. Signal Compensation Mode
- When the calibration is performed normally, the current measurement displays.
- It changes the value from current generator and checks whether the output is the same value.
- Pressing FUNC key calibrates the next channel
- Pressing RESET key moves to the previous calibration step.
- Pressing FUNC key for 2 sec or longer followed by password input enable menu selection.
- Use UP (▲) or DOWN (▼) key to select "CAL" (Calibration menu) then press FUNC key to move
-
to the channel selection menu to perform calibration.
- Press RESET key to return to measuring mode.
- By pressing UP (▲) or DOWN (▼) key, the user can move between channels (1-1 ~ 16-8) for
-
calibration.
- Pressing RESET key moves to the previous step.
- Using a current generator, input 20 mA output into the analog input terminal (positive/negative)
-
of the channel to be calibrated then press FUNC key to perform calibration.
- Pressing RESET key moves to the previous step.
- When the calibration runs normally, "CAL/SUCC" message flashes 2 times then it moves to the
-
next menu, which is test menu.
- When the calibration fails, "CAL/FAIL" message flashes 2 times then it moves to the previous
-
menu.
- Pressing FUNC key for 2 sec or longer followed by password input enable menu selection.
- Using UP (▲) or DOWN (▼) key, select "[F3]/SAD" then press FUNC key to perform calibration
-
on each channel.
- It is a function that compensates the difference from the wire.
- Press RESET key to return to measuring mode.
- By pressing UP (▲) or DOWN (▼) key, the user can move between channels (1-1 ~ 16-8) for
-
compensation.
- Pressing RESET key moves to the previous step.
