Preparing measurement

²Connecting ttemperature pprobe:

For the measurement of the line temperature and the automatic calculation

of super-heating and sub-cooling, a Pt100 temperature probe (accessory)

must be connected.

Probes must be connected before switching the instrument on, in order for

them to be recognized.

1Open the socket cover on the left-hand side of the instrument.

2Plug the connection plug of the temperature probe into the probe socket.

3Depending on the measurement task, position the probe at the end of the

evaporator (Superheat) or condenser (Sub-cooling).

²Switching iinstrument oon:

iPress .

²Zeroing ppressure ssensors:

Carry out a zeroing of the pressure sensors before each measurement.

The measurement values can be falsified by a change in the position of

the measuring instrument. After zeroing, the position of the measuring

instrument must not be changed. Carry out zeroing before every measure-

ment in order to compensate faulty positioning or long-term zero-point

drift. Zeroing is only possible in a range of ±1bar(rel)/ ±14.5psi (rel) and

0...2bar(abs)/ ±29psi (abs) resprectively.

The connections on the low and high pressure sides must be depres-

surized (ambient pressure).

1Press function button Set.

-p=0 flashes.

2Press OK to carry out zeroing.

²Connecting rrefigerant hhoses:

The valve knobs are closed.

1Connect refrigerant hoses for low pressure side (blue) and high pressure

side (red) to the instrument.

2Connect refrigerant hoses to the system.

²Measuring:

The handling steps from the chapter “Preparing measurement” have been

carried out.

1Pressurize the instrument.

2Read off measurement values:

For Zeotropic refrigerants (those with temperature glide), the tempera-

tures to/tc displayed are those at the end of the phase change

(evaporation or condensation) of the last component.
