To calibrate the current output value, take calibrating current 1 20mA as an example, first
connect the ammeter to the current 1 output terminal, then enter the menu “Test
Maintenance” -> “Current Cal” -> “Current 1 “ -> “Calibrate 20mA”. Press the key to
increase or decrease the value displayed on the screen until the ammeter reads 20mA,
then press the key
to save the calibration result.
All calibration and setting parameters of the instrument can be viewed.

7.7.5 Ambient temp
7.7.4 Measurement method
7.7.6 Meter reset
The instrument calibration parameters and all setting parameters can be reset to the
factory default state.
Ambient temperature value: Display the current ambient temperature value.
Ambient temperature calibration: Calibrate the ambient temperature measurement value of
the meter.
Buzzer alarm: Set whether the buzzer outputs an alarm sound when the ambient
temperature is alarmed.
Two current outputs can be tested. First, connect the ammeter to the current output
terminal to be tested, enter the menu and change the output current value by pressing
the key, and verify whether the meter current output is correct by the ammeter reading.

Note: When performing current calibration operation, for each current output, two points (4mA
and 20mA) need to be calibrated to achieve the calibration effect.
7.7.1 Current CAL
Two sets of relays can be tested for on or off.
After entering, select “close” or “open” and the corresponding relay will make an open or
close action.
The measurement value can be set to “Electrode measurement” or “Analog measurement”.
Electrode measurement: The measured value displayed on the screen is the value
measured by the electrode.
Analog measurement: The measured value is displayed as the input value set by the user.
