Selec an intalation site where:
_ mecal vibtion an shoc are neglect.le¡
_ no relaylp:er switche are in the direc envirnmt;
_ the anlyzer is not rrunted in diec suight an severe wether coitions.
_ maintence actvities are IXssible (no corrsive abnspheres)

3-2. Wiring.
(;erlly, trssion of signls representing the mesued pH or ORP value of a
liquid is by anlog, low voltages with ver high imce levels. Therefore,
disturbing influences mut be rninsed.
Before coiiectig sensor cales to the anyser inpit the following cotions mut
be considered:
- the senr cales are (preferably) not roted in trck together with high po
cales an cales with signls of switched high voltage or high. energy;
- the stada sensor cables are used;
- the anyser is mounted as nea as posible to the senrs (short senr cales).

1. Lose the tw screws on the front of the
anlyzer to rere the frot coer.
2. Thead the cales thgh the gla and
græmet as sh~ in fig. 3-8. Be sure to
plug any unuse: holes in the gramt. PUL
the cales into the inter assenly an
correcy coec each condctr to the
corresp:nding . te. Se also the
wiring diagr (pagrph 3-2-2).
NJ: When the ser imce che is
reqe: then connec liqud ea

If not, coect liqud ea to ter-
mil 1 8 (terl 14 is pa of the
mesuin circuit).
3. Scew the gla nut fi:y on th glan
l:y to keep out rristu. Hove, if the
gla nut is screwe on too tight, the
cales may be dage:.
3-2-2-2. Connecing the cales to the juncton 00.
'Ie junction b: an connecting cale are

For the wiring proure, see pagrph 3-2-2-1.
ID
1. When using a connecting cale be sure to
strip off the inulation. It is imrtat
tht the coctive layer is reme: fran
the p:lyethylene for a distace of at
least 5 nt.
2. The autantic imce check of the

As delivered, the 'I0 anlyzer is thoroughly tested at the factory an caletely
adjusted aCaJrdg users i reqirements. Inonntion is inicated on the data plate.
If not, the anlyzer setting is based on a default statu (basic factory settig).
If you have any problem, please aJntact yo neaest serice station of Yokogwa
Electrofact or Sales Agent. When enquing arut the anlyzer, provide the moel na
an serial num.
The anlyzer has a wide range of aJnfigution which ca be peorm by the use
accrdig to his s~ific 'reqemt.

InaJrrect use an setting of the anlyzer ca rest in a coed functionig. If
so, chec the prog values an cae then with the default values or the

Cbnfinn tht all wires are correcy connected over the entire systan (see
paagrph 3-2).

Supply the correct p: to the anyzer an plug in.
5-1-3. The magnetic cc.
It is not necsa to ope the case of the 'I0 anyzer for caibtion,
recnfiguation, etc. All halings are pefonned by a magnetic cader. '!s
ccer is place in a click-in hole on the front. For activating a key
(ree-relay), the ccer has to be place in the middle of the gree field.
5-2. Calibation.
The measuring loop for both pH an ORP mesuranents mut be caibted. A
description:is given in the pagrphs belCM.
5-2-1. Calibration of the mesuring loop for pH meaants.
Basically there are thee method:
1. bufer solution calibration
2. pross calibration
3. input of electre chacteristics.
5-2-1-1. Bufer solution calibtion.
Buffer solution calibration (or IIlifer
check") is pefonn using tw bufer solution.
The 1 st solution is for calibtion of the
offset voltage (asyitr lXtential of the pair
of electrodes). Geerlly, a value nea to the
isothenl lXint of intesection is chosen
(nornlly 7 pH).
The 2nd buffer solution is for calibration
of the seni ti vi ty of the electrodes (slope)
and usually, a buffer solution of 4 pH is coosen.
This solution has a high staility.
When bufer solutions accrding to the NB
stad are chosen, then the 'I0 anlyzer
recses these solutions an caibration is
perfonn. The NB stas are listed in
tale 5-1 (ST to ST5).
ID: The procure to ca out bufer ,
solution calibration is describ in: .
pagraph 5-3-4.
When no solution accordg to the NB
stada is used, then the value of the
solution ca be entered in the marry (see
paagrph 6, IIRecnfigliration of the
anlyzer II).
