For meter models with the analog output installed there is the option of sending out a signal from the meter as either voltage or current to an outside source. The strength of these signals is proportional to input signal from the load on the sensor. With this analog output option, it is necessary that the user enter the low input signal (An Lo) that will correspond to the low analog output and the high input signal (An Hi) that will correspond to the maximum analog output. The analog output voltage range is from 0-10 VDC. Your selection of either current or voltage must correspond to the output wire on your analog output board. Standard for Futek meters is the 0-10 VDC output, pin 2.
Setup:
Before beginning to program the meter for analog output function it is necessary to setup the wires. To use the voltage output, connect one wire to pin 2 and a ground wire to pin 3.
Configuration:
1. Press the left
Menu button and enter the setup mode. Continue to press the left
Menu button until An Set appears. Press the
Peak button.
NOTE: if An Set is not an option in your main menu: (1) make sure your meter has the analog output option, or (2) check the lock settings. The third digit (‘1100’) in Loc 2 refers to the ‘Analog Output Scaling’. Make sure this number is a zero. Exit the setup mode and then return. An Set will now appear as a main menu option.
2. ‘00’ will now appear on your display. Here you are to enter the type of output (current or voltage) and the analog output filtering. The first digit (‘00’) refers to the type of output. If you would like a current output leave the value at ‘0’. If you would like a voltage output the first digit should be a ‘1’. The second digit (‘00’) refers to analog output filtering. For an unfiltered source choose ‘0’. For a filtered source change the value to ‘1’. When you are done press the left Menu button.
3. An Lo will appear. Press the Peak button. Here you are to enter in the input signal that will correspond to the low analog output. For example, if you enter ‘00000’ then when ‘00000’ is on the display then 0 VDC will be outputted. Once your value is entered press the Menu key to store your value. An Hi will appear. Press the Peak button. Here you are to enter in the input signal that will correspond to the high analog output. For example if you enter in your max capacity, then an output of 10VDC will be outputted when max capacity is reached. Once your value is entered press the Menu key to store your value. Continue pressing the Menu key until you return to the run mode.
