the instrument

• the kind of cabinet

probe you have con-

nected is not right

• the cabinet probe

tor probe you have

connected is not

right

• the evaporator

of the instrument

REMEDIES

switch off the power

supply of the instru-

ment: unless the alarm

disappears, you will

have to change the

instrument

• look at the param-

eter /0

• test the integrity of

the probe

• test the instrument-

probe connection

• test the temperature

close to the probe (it

has to be between

the limits allowed by

the working range)

• look at the param-

eter /0

• test the integrity of

the probe

• test the instrument-

probe connection

• test the temperature

close to the probe (it

has to be between

the limits allowed by

the working range)
