ENGLISH

1Input A socket, DIN 8-pole connector

2Display

3REL: the symbol indicates that the instrument is storing the Maximum, Minimum and Q energy values

4MAX: the symbol indicates the maximum value of the chosen unit

5MIN: the symbol indicates the minimum value of the chosen unit

6A, B, A-B: the symbol indicates the relative value at the input A, B, or the differen- ce between the two inputs A-B

7AUTO: the symbol indicates that the automatic change of scale device is enabled

8°C/°F: key for selecting temperature reading in °C or °F

9lx/fcd: key for selecting reading in lx=lux or fcd=footcandle

10Data reset: the key erases the memory of the maximum, minimum and Q energy values and the integration time

11REC: when this key is pressed, the maximum, minimum and Q energy values and the integration time in seconds, minutes, hours, are stored and updated

12Itime: when this key is pressed in sequence, the integration time that has elapsed appears on the display in s=seconds, m=minutes and h=hours

13MAN: key for choosing the working scale manually

14S, Serial out: the key has two functions. The first of these, when pressing the Q key, makes the value advance towards the top of the acoustic alarm signal inter- vention threshold, the second enables the serial output for one item only and, if pressed for more than 3 seconds, enables the serial output continuously with a fixed rate of 10 seconds

15Q energy: when the key is pressed, followed by the Sand Gkeys, this sets the threshold value above which the alarm intervenes

16A: key for activating the display of input A

17A-B: key for activating the display of the difference between inputs A and B

18SUB D male 9-pole connector. The cable with electronics for the serial output RS232C, code AD RS232C, may be coupled to this connector

19Input B socket, DIN 8-pole connector

20X10-8: multiplication factor for the chosen unit; this may be 103, 106, -103, or -106

21lx: symbol indicating that the reading is in lux

22E/m-2•s: symbol indicating that the reading is in µEinstein

23fcd/m2: symbol indicating that the measurement is in footcandle m2

24°C: symbol indicating that the temperature measurement is in °C

25°F: symbol indicating that the temperature measurement is in °F

26Wm2: symbol indicating that the measurement is in Wm2

27Q energy: symbol indicating the quantity of energy in the integration time X

28m: integration time in minutes

29s: integration time in seconds

30h: integration time in hours

31ON/OFF: key for switching the instrument on or off

32DATA CALL: key for calling and reading on the display the stored maximum, mini- mum and Q values

33AUTO: this key enables the automatic change of scale function of the instrument

34G, after the Q energy key has been pressed, this key reduces the threshold value above which the acoustic alarm intervenes

35B: key for activating the display of input B.
