The serial data signal is made up of 16 bits in the following order:
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

The data bits carry the following information:

D15

Start signal

D14

4

D13

Display line indicator: 1 = upper line, 2 = lower line

D11+D12 Unit on the display: 

92 = m/s

2

93 = mm/s

94 = mm

95 = cm/s

96 = inch

97 = ft/s

2

98 = inch/s

57 = G

D10

Polarity: 0 = positive, 1 = negative

D9

Position of decimal point (DP) from right to left: 

0 = no DP, 1 = 1 DP, 2 = 2 DP, 3 = 3 DP

D8 down  Measuring result 

to 

D1

D8 = most significant bit (MSD), D1 = least significant bit (LSD).

If 1234 is displayed, the corresponding bit formation reads “00001234”.

D0

End signal

RS-232 settings: Baud rate: 9600, parity: none, data bits: 8, stop bit: 1 (9600, N, 8, 1)

Apart from battery replacements and occasional cleaning, the device is maintenance-free. Use a clean,
lint-free, antistatic and dry cloth to clean the device. Do not use any abrasive or chemical agents or
detergents containing solvents.

If the battery symbol 

appears on the display, the battery has to be replaced as soon as possible to

prevent faulty measurements. 

Proceed as follows to replace the battery:
- Switch off the meter
- Loosen the battery compartment screw on the back and slide the lid off the housing in the direction of

the arrow.

- Replace the used battery with a new alkaline battery of the same type (e.g. 1604A).
- Properly close the housing again in reverse order.
