Using current output function
The meter offers 0-20 mA and 4-20mA current output
functions.
Two output modes:
SOURCE mode: supply current from internal source;
SIMULATE mode (simulate): absorb current from
external source
Two Configuration modes:
Constant current output: constant output of designated
current.
Manual-step output: output current increases or
decreases in 25% or 100% step.
If you need to apply current for non-source circuit
(such as loop current without power), then select
SOURCE mode. The meter consumes more battery
power of being used as current source than that of being
used in SIMULATE mode, so select SIMULATE mode if
possible.
