6.3.2 Filling the micro calibration bath

1. Firstly, remove the transport cover.

2. Place the test item in the sensor basket.

3. Fill the tank with calibration liquid.

Following maximum lling heights are recommended:

Calibrator model max. lling height

CTB9100-165 / CTM9100-150 130 mm

CTB9100-165 / CTM9100-150

with removable insert

110 mm

CTB9100-225 123 mm

CTB9100-225

with removable insert

105 mm

CTB9100-225-X 115 mm

CTB9100-225-X

with removable insert

95 mm

Following points should be observed at the maximum

lling heights:

■

Measured from the bottom of the sensor basekt

■

Non loaded tank

■

WIKA standard lling liquid

■

Pre-lling ex-works with the optimal height

The transport cover is tted with a safety

valve. If the micro calibration bath is closed

when it is still warm, excessive pressure

can build up. In order to avoid overpres-

suring, which could lead to damage to the

liquid bath, the safety valve is activated at a

pressure of approx. 2.5 bar. This can lead to

hot vapour escaping.

6.3.3 Operation of the magnetic stirrer

The greatest possible homogeneity is achieved by the agita-

tion of the calibration liquid via a magnetic stirrer.

Set the stirring speed to the maximum possible. Turning the

wheel upwards will increase the speed, turning it downwards

slows down the stirring speed.

The magnetic stirrer is a

consumable.

6.3.4 Insert for liquids

The insert for liquids consists of:

■

Insert with leak-proof cover

■

Sensor basket

■

Magnetic stirrer and lifter

■

Replacement tools

If the insert for liquids is ordered with a new

model CTB9100 micro calibration bath or a

new model CTM9100 multi-function calibra-

tor, the instrument will have been matched to

the insert for liquids.

Should the insert for liquids be ordered after-

wards, a re-adjustment of the instrument at

the customer’s will be needed.

WARNING!

The insert for liquids must only be removed if

the calibrator is used at room temperature.

CAUTION!

The ll level must be matched the relevant

medium and the temperature.
