Programming an Output in Percent (Current and Voltage Outputs Only)

Output values can also be programmed in percent. For example, a 4 to 20mA output can

be programmed as follows: 0% = 4mA, 50% = 12mA, and 100% = 20mA. The main LCD

digits will reflect the actual output while the top (smaller) digits will display the percentage.

Follow these steps to output a signal in percent:

1. Setup a test as described earlier for a current or voltage output.

2. Press the SHIFT button so that the word SHIFT appears on the LCD.

3. Press the % key.

4. Enter a percentage from 0 to 100% (1% resolution) using the numeric keys.

5. Press the ENTER key.

6. The current or voltage signal will be output from the meter.

7. 0% corresponds to the lowest value in the range ('4mA' for 4 to 20mA, '0mV' for 0 to

100mV, for example.) while 100% corresponds to the highest value in the output range

('20mA' for 4 to 20mA range, '100mV' for 0 to 100mV range). All percentages in

between will be linear to the voltage or current ranges.

8. Refer to the list below for the 1% step value for each range:

4 to 20mA:

1% = 0.16mA

0 to 20mA:

1% = 0.2mA

0 to 24mA:

1% = 0.24mA

0 to 100mV:

1% = 1mV

0 to 1V:

1% = 0.01V

0 to 12V:

1% = 0.12V

Step Mode (Current and Voltage Outputs Only)

This feature allows the user to step up and down through the output range in programmed

steps as follows:

1. Setup a test as described earlier for a current or voltage output.

2. Press the SHIFT key and then the % key.

3. Enter a percentage (1 to 100%) using the numeric keys. This percentage will represent

the size of each step. Press the ENTER key when complete.

4. Now each time the '8 %

' key is pressed, the output signal will be increased by the

percentage programmed (in the previous step). Press the '0 %

' key to step the

output down by the percentage programmed.

5. For example, for a 4 to 20mA output type and a step percentage of 25%, the following

steps are possible:

0% = 4mA

25% = 8mA

50% = 12mA

75% = 16mA

100% = 20mA
