8. Press MENU t st re the value sh wn f r RD!1 .
The unit displays:
T define the maximum l ad (IN!2 and RD!2 ):
1. Repeat steps 3–8 above, entering the values or IN!2

2. Once y u've c mpleted all steps, the unit displays:
T begin perati n:
Reinitialize the unit (press RESET twice r
press MENU until RST flashes n the
display). When a numeric reading appears,
the unit is perati nal.
Determining Reading Offset
The run m de reading f r meters scaled with ut kn wn l ads may
reflect an ffset. F r example, say y u set
RD!1
t 0 and
RD!2
t
100, but when the minimum l ad is applied, a negative value f –1.5
displays n the fr nt panel.
T c rrect the reading ffset:
1. With zer l ad applied, n te the reading n the display.
2. Subtract that am unt fr m the RD!1 and RD!2 values y u
riginally entered.
In the example, the ffset w uld be –1.5. If RD!1 is t read 0 in
Run M de, it must be reentered as 1.5. RD!2 must likewise be
reentered as 101.5 if the meter is t read 100 when the
maximum l ad is applied.
3.
Repeat the steps f r "Scaling With ut Kn wn L ads," but when
the values f r IN!1 and IN!2 display, d n t change them.
Instead, press MENU t m ve t the pr mpts f r RD!1 and RD!2
and make the necessary changes.
4. Reinitialize the unit and resume perati n.
