The “Operating M de” f ll ws the “Setup” screen.
The display sh ws the status f the f ur sets f utputs (simulate) and inputs
(read).
In fr nt f each f the simulate utput readings will be either an up arr w r a
d wn arr w. The up arr w indicates the Quadcal is s urcing the current f r that
l p, and the d wn arr w indicates the Quadcal is just sinking current f r that
l p. Next is the reading that l p is set t and then the display m de (MA r
%). If the l p is n t c nnected r is set up as “sinking” when it sh uld be
‘s urcing”, the reading will be “Open”, instead f the setting f r that l p.
The right side f the display f r that l p pair will sh w either the current
sensed in that input l p, r the percent f the 4/20 reading (%) ass ciated
with that current l p. If the reading is n n-existent due t the l p being pen,
r much bel w 3.5MA, the display will sh w “OPEN” instead f a current/percentage reading.
If y u need t change the perating m de f r the unit, pressing the ‘1’ & ‘2’ kn bs at the same
time will return the Quadcal t the “SETUP MODE”.
CHANGING AN OUTPUT CURRENT OR PERCENTAGE:
There are several ways f changing the current utput f a channel:
Turning the kn b f the channel ne ‘click’ will change the current setting by either 0.25MA r
.25%, depending n the utput m de selected f r that channel.
Pressing the kn b d wn and turning it while pressed d wn will change the current setting by
either 0.01MA r 0.01%, depending n the utput m de f r that channel.
Pressing and releasing the kn b with ut turning it will cause the channels utput t step
between the current reading and ne f three presets (see PRESETS ADJUST) f r the channel.
The initial presets are 4MA, 12MA and 20MA r 0%, 50% and 100%, depending n the
perating m de selected f r that channel.
PRESETS ADJUST:
This m de is entered fr m the OPERATING MODE by pressing b th the ‘1’ & ‘3’ kn bs at the
same time.
