6. Calibration

General Instructions

Information:

The Hygropin probes have an imprinted characteristic.

The following procedure explains a 3-point calibration to re-adjust the in-situ and ambient probe.

The 3-point calibration is conducted with 3 different humidity standards which are traceable to na-

tional standards: 10%RH, 35%RH and 80%RH.

The temperature sensor must not be calibrated. Reason: unnecessary due minimal drift, source of

errors and required equipment goes beyond the scope of ASPO.

Please consider following in general:

- Room temperature: 23°C ±2K

- No drafts in the calibration room.

- No direct sunshine.

- The values of the humidity standards apply at 23°C.

- If the temperature is different from the standard temperature of 23°C, the corresponding value of

the humidity standard has to be taken into account.

Attention :

Probe, calibrating device and the humidity standard must be at the same temperature.

1K temperature difference between the humidity standard and probe can result in up

6%RH humidity error.

Preparation of Calibration Device

Procedure :

Remove the knurled lid of the calibration device.

Insert the probe carefully into the calibration cham-

ber and seal it by screwing the holder.

Place a textile pad in the lid of the calibration

device.

Preparation of Humidity Standard

Procedure :

Hold the ampoule of the selected humidity standard

at the neck and bring the entire contents into the

further, lower part of the ampoule by swinging or

lightly tapping against the glass.

Apply Humidity Standard

Procedure :

Break the ampoule at the marked area and empty it

completely on the center of the textile pad while

tapping it lightly.

Doc: 820 78 004E Rev: 02 Page 10/14

Close calibration device

Procedure:

Align the calibration chamber with the probe so that

the opening for the lid points downwards. Screw on

the lid with calibration solution carefully. The probe

or screw-in thread may not come into contact with

the moisten textile pad.

Equilibrium time

Procedure:

Place the probe together with the calibration device

on the cover of the humidity standard box applied.

Switch on the Hygropin and wait.

The waiting time to reach the humidity equilibrium

depends on the humidity standard:

10%RH 45min

35%RH 45min

80%RH 60min

Humidity Calibration with Hygropin

Procedure :

Press and select the probe to calibrate.

Press to activate the Probe 1 or Probe 2

menu item.

Use to select “Humi Adjust”

Press to confirm and open the sub-menu.

Use to select the “Acquire (Enter Ref)” menu

item and press to confirm.
