Setting 0% and 100% Output Parameters
•
Users need to set the values of 0% and 100% for the step operation and
percentage display. Some values of the calibrator have been set as default.
•
The table below lists the factory settings.
Output Functions
0% value
100% Value
Current
4.000mA
20.000mA
•
These factory settings may not be suitable for your work, you can reset them
according to your requirements.
•
Adjust the output value with four VALUE buttons, long press BACKLIGHT or
SLOPE/STEP until the buzzer makes a “beep” sound to set the new values of 0%
and 100%. The newly set range is automatically saved in the calibrator storage
area, and it is still valid after restarting.
•
Now you can use the settings to do the following:
•
Long press UP or DOWN (25%) to manually step (increase or decrease) the output
in 25% increments.
•
Long press LEFT (0%) or RIGHT (100%) to switch the output between 0% and
100% range.
Auto Ramping (inc/dec) the Output
•
The auto ramping function allows you to continuously apply a varying signal from
the calibrator to the transmitter and view the calibrators response.
•
Press the SLOPE/STEP button and the calibrator will generate a continuous and
repeating 0% - 100% ramping output.
•
Three types of ramping waveforms are available:
1. 0%-100%-0% 40 second smooth ramp
2. 0%-100%-0% 15 second smooth ramp
3. 0%-100%-0% 25% step ramp pausing for 5 seconds at each step
•
Press any key to exit the ramping output function.
Restore Factory Settings
•
Long press the RTD button while powering on the calibration until the buzzer
sounds. After the factory reset is completes the calibrator will automatically enter
into the operating mode.
•
The following factory settings are restored:
1. Operating mode: voltage output mode
2.
Auto power off time: 30 mins (enabled)
3. LCD backlight brightness: 60%
4. Output range
