Operation

6.1 Measurement preparation

Before using the meter for the first time, insert the batteries correctly as described in chapter 7The batteries are absolutely necessary to operate the internal clock when
the meter is switched off.
Insert an SD card into the card slot. Format the card before using it for the first time or if the card has been formatted by other devices. To format the SD card, proceed as
described in chapter 6.7.1
Switch on the instrument with the “▼ / Power” key.
Check the date, time and log interval. Press the “▲ / Time” key for approx. 2 seconds.
The set values are displayed one after the other. You can change the date, time and log interval as described in chapter 6.7.3
Make sure that the decimal character is set correctly. The default decimal character is a dot. In Europe, however, the comma is customary. If the decimal character is not set
correctly in your country, this can lead to incorrect values and complications when reading out the memory card. You can make the setting as described under chapter
Enable or disable the key and control sound as described in chapter 6.7.4
Enable or disable the RS232 output as described in chapter 6.7.6
Connect the signal line to the corresponding plugs of the measuring inputs, observing correct polarity.

6.2 Display information

SD card is full or defective.
Empty and format the SD card.
If the indicator continues to appear, replace the SD card.

Battery level low
Replace the batteries.

No SD card inserted
6.3 Measuring/logging

Plug the measuring input connectors into the corresponding channel input, observing correct polarity.
Switch on the meter with the “▼ / Power” key.
The current measured values are displayed.

6.3.1 Starting the log function

To start the logger, press and hold the “LOG / Enter” key for 2 seconds. “Scan” appears briefly in the upper part of the display as confirmation. “Datalogger” appears
between the displays for channels 2 and 3. The lettering “Datalogger” flashes and the control sound is audible at the set log interval (if not disabled).

6.3.2 Exiting the log function

To exit the log function, press and hold the “LOG / Enter” key for 2 seconds. The unit returns to the measuring mode.

6.4 Backlight
6.4.1 Battery operation
Press the “▼ / Power” key to switch on the display backlight for approx. 6 seconds when the meter is switched on.

6.4.2 Mains operation
Press the “▼ / Power” key to switch the display backlight on or off when the meter is switched on.

6.5 Switching the meter off and on

If necessary, disconnect the plug-in mains adaptor from the mains and from the meter.
Press and hold the “▼ / Power” key for 2 seconds.
To switch the meter back on, press and release the “▼ / Power” key once.

It is not possible to switch off the meter while power is supplied by the mains adaptor.
6.6 Data transfer to the PC

Remove the SD card from the meter when the log function is finished.
Attention!
Removing the SD card while the log function is active can lead to data loss.
Insert the SD card into the corresponding SD card slot on the PC or into an SD card reader connected to the PC.
Start the spreadsheet program on your PC, open the file on the SD card and read out the data.

6.6.1 SD card structure
The following structure is automatically created on the SD card when it is used for the first time or after formatting:

Folder “MAA01
File “MAA01001” with max. 30000 data records
File “MAA01002” with max. 30000 records if MAA01001 overflows.
etc. until “MAA01099
File “MAA02001” if MAA01099 overflows
etc. until “MAA10….

Example file

6.7 Advanced settings

With the meter switched on and the data logger not activated, press and hold the “SET” key until “Set” appears on the display.
With the “SET” key, you can call up the following setting options one after the other.

3| SP-t| Sampling time/log interval
4| bEEP| Key / control sound on / off
5| dEC| Decimal character . or 1
6| rS232| RS 232 output on / off

If no entries are made for 5 seconds, the unit returns to the measuring mode.

6.7.1 Format SD card

Navigate to the advanced settings as described above.
The prompt Sd F appears on the display.
Use the “▼ / Power” or “▲ / Time” key to select yes or no.
Confirm the selection with the “LOG / Enter” key.
If you select yes, you must confirm the security query again with the “LOG / Enter” key.
Press the “SET” key repeatedly until you return to measuring mode or wait 5 seconds; the meter will then switch to measuring mode automatically.

If you select yes and confirm the security query, all data on the SD card will be deleted and the SD card will be reformatted.

6.7.2 Date / time

Navigate to the advanced settings as described above.
Press the “SET” key repeatedly until “dAtE” appears on the display.
After a short time, the year, month and day appear on the display.
Use the “▼ / Power” or “▲ / Time” keys to select the current year and confirm the entry with the “LOG / Enter” key.
Proceed with entering the month and the day as you have entered the year. After confirming the day, the hour, minute and second appear on the display.
Proceed with these entries as with the year, etc.
Press the “SET” key repeatedly until you return to measuring mode or wait 5 seconds; the meter will then switch to measuring mode automatically.

6.7.3 Sampling time/log interval

Navigate to the advanced settings as described above.
Press the “SET” key repeatedly until “SP-t” appears on the display.
Select the desired log interval with the “▼ / Power” or “▲ / Time” keys and confirm the
entry with the “LOG / Enter” key. The following can be selected: 1, 2, 5, 10, 30, 60, 120, 300, 600 seconds and auto.
Press the “SET” key repeatedly until you return to measuring mode or wait 5 seconds; the meter will then switch to measuring mode automatically.

Close the battery compartment and fasten the locking screw.

Reset system

If a serious system error occurs, resetting the system can solve the problem. To do this, press the reset key with a thin object while the meter is switched on. Note that this resets the advanced settings to the factory default.

RS232 interface

The instrument has an RS232 interface via a 3.5 mm socket. The output is a 16-digit data string that can be set up according to user-specific requirements. An RS232 cable with the following features is required to connect the meter to a PC:

The 16-digit data string is displayed in the following format:
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
The numbers stand for the following parameters:

D15	Start word
D14	4
D13	When upper display data is sent, 1 is sent When medium display data is

sent, 2 is sent When lower display data is sent, 3 is sent
D12 & D11| Annunciator for display mA = 37
D10| Polarity
0 = Positive 1 = Negative
D9| Decimal point (DP), position from right to left 0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
D8 to D1| Display indication, D1 = LSD, D8 = MSD For example:
If display is 1234, D8 … D1 is 00001234
DO| End word
Baud rate| 9600
---|---
Parity| No parity
Data bit no.| 8 data bits
Stop bit| 1 stop bit
