Section 4
Defragment: Selecting [YES] for this item consolidates memory data blocks into contiguous storage;
collapsing the filler regions. You may be able to use an additional block for site or datalogger storage as
a result. Use this command if you seem to be out of memory even though the [Data Memory Left] item
indicates free capacity.

4.12.5 THE ANALOG OUTPUT TRIM MENU

Analog Output Trim allows you to fine-tune the meter's analog voltage and current outputs using a multi-
meter connected to the output under test. In addition, you can use a frequency counter to fine-tune the
meter's pulse rate output.
NOTE: The current, voltage, and Pgen trimming will be limited by the 12-bit resolution of the
flowmeter's D/A Convertor (DAC).
Press the <Right Arrow> to access the [Analog Output Trim] menu.

NOTE: See drawing 1010N-7-7 if using Expanded I/O Module.
Current Output Trim (Io1 & Io2)
(Note: Can be trimmed to within .005 mA of nominal.)
To calibrate a current output (Io1 or Io2):
1. Set up the multimeter to read Amps, then connect it to the supply and return terminals of the current
output under test.
2. Move the highlight to the port to be tested, press the <Right Arrow>, then press the <Down Arrow>
to move the cursor to [Trim @ 4mA].
3. Press <ENT>. This triggers a 4.00 mA pop-up window. The multimeter should now be reading 4.00
mA.
4. If the multimeter reading does not match, use the numeric keys to type in the multimeter reading.
5. Press <ENT> to register setting. This adjusts the meter's DAC (digital-to-analog converter) so that a
4mA output corresponds with 4mA on the multimeter.
6. Re-check the multimeter to make sure that it is now reading 4mA.
Voltage Output Trim (Vo1 & Vo2)
(Note: Can be trimmed to within .0025 V of nominal.)
To calibrate a voltage output (Vo1 or Vo2):
1. Set up the multimeter to read volts, then connect it to the supply and return terminals of the voltage
output under test.
2. Move the highlight to the port to be tested, press the <Right Arrow>, then press the <Down Arrow>
to move the cursor to [Trim @ 2V].
