5. Adjust the output value using the up and down keys until the
multimeter shows the output value required at minimum input,
e.g., 4 mA for a 4-20 mA output.
6. When you are satisfied with the output, press the ENT button.
The middle LED will switch on to indicate that you are calibrating
the maximum input and corresponding output values.
7. Set the input source to the maximum value required, e.g., 20 mA
for a 4-20 mA signal.
8. Adjust the output using the up and down keys until the output is
at the value required at maximum input, e.g., 20 mA for a 4-20
mA output.
9. Once all settings are completed press ENT twice. The ‘Ready
to save’ LED will switch on then turn off. After two seconds the
instrument will return to normal operation (with the Status LED
