15. CAL - Checking and/or Calibrating 4-20 or 0-1mA output and Voltage reading
Note: Use a certified digital multimeter which meets or exceeds the accuracy and resolution of your system
Timeout of CAL mode in 2 min if no buttons are pressed
1. Connect the DC current meter’s positive (+) lead to TB2-16 and the negative (-) lead to TB2-17,
2. ILO (low current limit) annunciator will be displayed, refer to operation flow diagram on page 10
3. Use the UP/DOWN button to adjust (if necessary) the low current limit to 4.00mA
4. Short-press the LIMIT button and go to the next calibration point, IHI (high current limit)
5. Use the UP/DOWN button to adjust (if necessary) the high current limit to 20.00mA
6. Connect the voltage input leads of your digital multimeter to TB1-1 and TB1-2
7. Short-press the LIMIT button and go to the next calibration point, VCAL
8. Use the UP/DOWN button to adjust (if necessary) the voltage readout to match the multimeter
Adjust 20.00 mA or 1.00 mA s
Adjust battery monitor voltage readout
9. Exit menu, press and hold LIMIT button for approx. 4 sec
