CALIBRATION
1) GEN ERAL
• The power sup plies are fac tory cal i brated
and nor mally need no fur ther cal i bra tion.
Only in spe cial sit u a tions (for ex am ple af ter
re pair ing a unit) cal i bra tion can be nec es -
sary.
2) METER CAL I BRA TION
• DIG I TAL ME TERS
The full scale in di ca tion can be cal i brated
with R25_31 and R25_36 on P596 (see
fig. 4 - 17).
3) SPE CIAL CAL I BRA TIONS
• The fol low ing cal i bra tions must be done by
qual i fied per son nel only. Wrong cal i bra tion
causes mal func tion. These cal i bra tions are
only needed af ter spe cial re pairs.
Warn ing ! Dam age caused by wrong
cal i bra tion is not war ranted.
• CAL I BRATING THE CUR RENT
MON I TOR OFF SET.
With R26_73 on P597 the off set of the CC
mon i tor volt age can be cal i brated (see fig.
4 - 18). The unit has to be un loaded, the out -
put volt age has to be turned off us ing the
OUT PUT ON/OFF button. Mea sure the off -
set volt age of the CC mon i tor on the pro -
gram ming con nec tor. Cal i brate the off set on
a neg a tive value be tween –1 mV and zero
mV.
Warn ing! wrong cal i bra tion can dam age
the unit.
• CAL I BRAT ING MAX. CUR RENT RANGE
or CAL I BRAT ING CC MON I TOR FULL
SCALE.
Short the out put us ing a low re sis tive ca ble.
Mea sure the out put cur rent with an ac cu rate
shunt. The max i mum out put cur rent can be
cal i brated with R26_41. R26_41 is lo cated
on P597 (see fig. 4 - 18).
Pro gram CC in put with ex actly 5.00 V.
Set out put volt age to a high value, en sur ing
the power sup ply is in CC mode. Cal i brate
the cur rent with R26_41 ex actly on the rated
max i mum cur rent.
Warn ing! Wrong cal i bra tion can dam age
the unit.
