5 Inserting or replacing batteries

If the battery is discharged, it is possible that the meter can no longer be switched on or that the

measured values are no longer within the specified accuracies.

To insert or replace the batteries, first switch off the meter. Open the battery compartment on the

back, remove the batteries if necessary and replace them with 2 new 1.5 V batteries. Ensure that

the polarity is correct when inserting the batteries.

6 Switching the meter on and off

To switch on the meter, press and hold the on and off switch for two seconds. After switching on,

the measurement can be carried out immediately. To switch the meter off again, press and hold

the switch again for two seconds.

6.1 Menu

To make settings, press the menu key. The arrow keys can now be used to select between the

individual setting options and to change parameters. Press the enter key to accept the respective

setting or open the setting option. Use the back key to go back one level if settings are not to be

accepted or the measurement is to be resumed.

The menu is organised as follows:

Function

Meaning

Work mode

Settings for the individual operating modes

Fe/NFe

Setting the measurement method

Units

Setting the unit of coating thickness

measurement

Environment

Setting the temperature, humidity and dew

point

Calibration

User settings

Other settings for the meter

6.1.1 Set work mode

To set the work mode, go to the settings and select "Work mode". Here, you can switch between

the individual work modes.

6.1.1.1 Switch work mode

To switch to a different work mode, select the desired work mode under "Mode select". You can

choose between "Group" and "SSPC (Society of Protective Coatings)"

6.1.1.2 Set group mode

To choose between the individual groups, go to "Group select" where you can choose between

50 different groups where the measured values are saved. The number of measured values

already saved is displayed for each group. 50 measured values can be saved for each group.

No measured values are saved with "Direct".

6.1.1.3 Set SSPC mode

To set the SSPC mode, go to "SSPC mode". The number of measuring points can be set there.

Function

Meaning

Smallest value: 3

Spots/Area

Number of surface that are measured

Smallest value: 5

Note: The limit values are taken from the limitvaluefunction. Seealso 6.1.6 Set alarm limit values.

6.1.1.4 Clear memory

To clear the memory, go to "Clear Memory". If you really want to clear the memory, confirm the

entry by selecting "Yes".

6.1.2 Ferrous and non-ferrous measuring substance

To switch between the measurement of ferrous (Fe) and non-ferrous (NFe) metals, go to "Fe/NFe"

in the settings. Here, you can select which method should be used for measurement. The

measurement method is automatically selected if you choose "Both".

Note: It is recommended to select "Both".

6.1.3 Set units

To set the coating thickness unit, go to "Units" in the menu. The coating thickness unit can be set

there. The following options are available: µm, mm, mils, inch.

6.1.4 Change temperature, humidity and dew point

To set the temperature, humidity and dew point, go to the menu and select "Environment". From

there, you can set which measured values are to be displayed. The following options are

available:

Selection

Meaning

Temp only

Temperature display

Temp/Humidity

Display of temperature and humidity

Temp/Dew Point

Display of temperature and dew point

Enviro off

No display

6.1.4.1 Set temperature unit

To set the temperature unit, go to "Units". From there, you can change the temperature unit. You

can choose either °C or °F.

6.1.5 Calibration

To calibrate the meter, go to "Calibration" in the settings.

There are four different options for calibration:

Selection

Meaning

Zero Only

Calibration of the zero point

Single Point

Zero point calibration with calibration of a

reference

SSPC Mode 1

Calibration of a reference

SSPC Mode 2

Calibration with two references

Reset

Reset all calibration points

Select the desired function and follow the instructions on the display. Depending on the selection,

a calibration must first be carried out on the zero standard or with a reference foil. If calibration is

carried out with reference foils, the measured value can be adjusted using the arrow keys after

the measurement with a reference.

6.1.6 Set alarm limit values

To set the alarm limits for the measurement, go to the "Limits" item in the menu.

6.1.6.1 Switching the limit value alarm on and off

To switch the limit alarm function on and off, switch "Limit" on or off.

6.1.6.2 Setting the limit value alarm indicator

To set the limit value alarm indicator, go to "Warning Indication".

The following settings can be made from there.

Setting option

Meaning

Beeper

An acoustic signal is emitted as soon as the set limit value is

exceeded.

Note: The sound must be active in the settings for the signal

tone to be active.

LED Flash

The LED indicator signals whether the measured value is within

the set limit value.

Both

Both the acoustic signal and the LED indicator show whether

the measured value is within the set limit values.

Note: The sound must be active in the settings for the signal

tone to be active.

Off

No signal when limit values are exceeded

6.1.6.3 Set alarm limit values

Go to "Set High Limit" to set the upper alarm limit value. To set the lower limit value, go to "Set

Low Limit".
