The Sigma C ntr ls Quadcal calibrat r is designed t generate (simulate) 4 is lated channels f
4/20MA signals sink/s urce and read 4 Channels (sink) f 4/20MA inputs that share a c mm n
return but are is lated fr m the 4 utputs. The inputs are pr tected fr m accidental ver
currents by means f resettable fuses and p larity pr tecti n and clamp di des.
The display res luti n is f r 2 digits after the decimal p int f r b th the inputs and utputs.
DC p wer c nnecti n.
The unit is p wered by a 5 VDC 1A “plug in” p wer supply r USB c nnecti n. The barrel jack
supply c nnecti n is n the t p f the unit.
N te: The center pin n the c nnect r must be the p sitive (+) f the DC supply.

SETUP MODE:
When p wer is first applied, a “splash screen” is displayed which sh ws its m del name,
c pyright inf rmati n, the current l aded s ftware versi ns, and the date and time acc rding t
its internal cl ck.
F ll wing the intr duct ry screen c mes the “Setup Screen” which all ws f r perating
parameter selecti n. It all ws y u t set if an utput channel is in s urce (p wer supplied
internally f r the l p) r sink m de (emulating a 4/20MA l p p wered device). It
als all ws y u t select the display m de f r the ( utput) channel (MA r %), and
the display m de f r the c rresp nding input channel (MA r %). This is
acc mplished by turning the c rresp nding kn b f r that channel pair until the
c rrect selecti n is sh wn. The p ssible ch ices f r each channel are: SRCE MA
– SHOW MA, SRCE % - SHOW MA SRCE MA – SHOW %, SINK MA – SHOW
MA, SINK % - SHOW MA, SINK MA – SHOW % and SINK % - SHOW %. These
ch ices are independent f r each f the channel pairs.
Setup m de can als be entered by pressing the 1 and 2 keys at the same time.
When the selecti ns are c rrect f r y ur applicati n, press the ‘3’ and ‘4’ kn bs at
the same time t save the settings. The unit will remember y ur setting when y u
apply p wer t the unit the next time.
OPERATING MODE:
Set Channel 1 t supply
the l p v ltage and vary
its milliamps. Display
value in mA
Set Channel 4 t vary
the milliamps f a
p wered l p. Display
value in %
Set Channel 1 t
measure a p wered 4-
20mA signal. Display
value in mA.

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.

6
In this m de, kn b ‘1’ is used t select the channel (1-4) t select f r changing presets, kn b ‘2’
is used t select which preset (1-3), kn b ‘3’ is used t change the preset, and kn b ‘4’ is used
t st re the change. If y u d n t press and release kn b ‘4’, the value f r that channel/preset
will NOT be changed. N te that there are 6 presets st red f r each utput channel: 3 f r MA
m de, and 3 f r percent (%) m de perati n, and the presets f r each channel are selected
based n the perating m de f r that channel.
As in OPERATING MODE, pressing kn b ‘3’ while turning will all w changing f the preset in
0.01MA r 0.01% steps, instead f 0.25MA r 0.25% steps.
T exit back t OPERATING MODE, press b th kn bs ‘3’ and ‘4’ at the same time.
These settings are als remembered by the unit.
DISPLAY ADJUST:
This m de lets y u adjust the display c ntrast and back light brightness.
T enter the m de fr m the OPERATING MODE, press b th the ‘2’ and ‘4’ kn bs at the same
time.
Turn kn b ‘1’ t adjust the c ntrast f the display and kn b ‘2’ t adjust the back light brightness.
Press kn bs ‘3’ and ‘4’ at the same time t return t OPERATING MODE.
These settings are als remembered by the unit.
DATE/TIME ADJUST:
This m de is primarily f r future expansi n when s ftware upgrades will all w the Quadcal t d
data l gging and/ r run ‘canned’ test sequences al ng with the data l gging.
The date/time are st red in a battery backed cl ck chip in the Quadcal.
T enter the m de, press the ‘1’ and ‘4’ kn bs at the same time.
Use kn b ‘1’ t select the date/time settings t change – they are indicated by the underlining f
the digits that are t be changed.
Use kn b ‘2’ t change the value f the displayed date/time inf rmati n.
Press kn bs ‘3’ and ‘4’ at the same time t return t OPERATING MODE.
