Calibrating 20 mA Output
1.
Connect the mA receiving device to the device.
2. Put the device into Navigation View.
3. Set Milliamp Output (2.5.9.) (Page 182) to 20.0 for the selected mA output.
4. View the mA level on the receiving device.
5. If there is a discrepancy, do the following steps:
–
Attach an ammeter to the device's mA output.
– Enter the exact value displayed on the ammeter into 20 mA Output Trim (2.5.12.)
(Page 183)
– The ammeter should then read exactly 20.00 mA.
The unit is now calibrated for 20 mA for the receiving device.
7.7 Volume
Volume is used in two situations:
1.
To calculate and display Volume instead of Level.
2. To calculate pumped volume to accomplish the following:
● Totalize the volume of material that is pumped out of the wet well
● Set an alarm on pump efficiency
7.7.1 Readings
When using volume, volume values are presented in the same units specified in Maximum
Volume (2.7.3.) (Page 188). The default is 100, which gives a reading in percent of total. Use
whatever unit is applicable. If the value is too large for the six-digit LCD, use a larger unit.
