Device description

Making a measurement

First switch on the meter by pressing and holding the on/off key. To switch off the meter, you must also keep this key pressed. As soon as the meter is switched on, the measurement starts directly with the last measurement function used.
To select between the individual measuring functions, press the function key repeatedly.

The following functions are available:

Stroboscope

To make a measurement with the stroboscope function, select the “Scope” function. Align the LEDs in the direction of the test object. Now set the speed using the arrow keys. To double or halve the rotation speed, hold down the double button and then use the arrow keys.

Optical speed measurement
To make an optical speed measurement, select the “Photo” function. Stick a 1 x 1 cm piece of reflective tape onto the test object. Now switch on the test object and direct the light cone so that it shines on the reflective tape. The speed of rotation is measured. Next to the measured value, an indicator flashes once briefly as soon as the reflective tape has been recognised.

Contact revolution measurement
To make a contact revolution measurement, select the “touch” function. Plug the desired adaptor onto the meter. Select the unit “RPM” with the UNIT key. Now carry out the measurement on the test object.
Note:
The wheel attachment is only intended for speed measurement.

Contacting speed measurement
To make a contact speed measurement, select the “touch” function. Place the wheel attachment on the meter. Press the UNIT key repeatedly until the desired unit is displayed. You can then carry out the speed measurement.

Temperature measurement with a thermocouple
To perform a temperature measurement, select the “type” function. Insert a K-type thermocouple into the meter. The measured value appears on the display.

Temperature measurement with a PT 1000 temperature sensor
To carry out a temperature measurement, select the “pt” function. Insert a PT 1000 resistance temperature probe into the meter. The measured value is displayed directly.

Freezing measured value (HOLD)
To freeze the displayed reading, press the Hold key. “HOLD” appears on the display. To resume the measurement, press the Hold key again.

Highest and lowest measured value (REC)
Press the REC key. “REC” is displayed on the screen. To view the highest and lowest readings, press the REC key repeatedly. Press and hold the REC key to disable this function.
As soon as this function has been switched off, the values are reset.

Settings

Automatic power-off
To enable or disable the automatic power off function, press and hold the function key for at least 5 seconds. The arrow keys can now be used to enable or disable automatic power off. Press the REC key to accept the setting. Use the on/off key to return to measurement mode.
Note : The “HOLD” and “REC” functions must be switched off.

Changing the temperature unit
Press and hold the function key for about 5 seconds. Then press the function key again to change the temperature unit. The temperature unit can now be changed with the arrow keys. Press the REC key to accept the setting. Press the ON/OFF key to return to measurement mode.
Note:
The “HOLD” and “REC” functions must be switched off.
When the function is switched off, the values are reset.

Replacing the batteries

To insert or replace the batteries, first switch off the meter. Then open the battery compartment and replace the batteries. Ensure correct polarity of the batteries. Use four 1.5 V AA batteries.

RS232 interface

The unit has a serial RS232 interface with a 3.5 mm output. The data output is via a 16-digit stream which can be used for your specific applications.
An RS232 guide with the following connection is required to connect the meter to a serial PC output.

The 16-digit streams are displayed as follows:
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Each digit indicates the following status

RS232 format : 9600, N, 8, 1
