QUANTUM - PHOTO - RADIOMETER
1 Input A socket, DIN 8-pole connector
2 Display
3 REL: the symbol indicates that the instrument is storing the Maximum, Minimum
and Q energy values
4 MAX: the symbol indicates the maximum value of the chosen unit
5 MIN: the symbol indicates the minimum value of the chosen unit
6 A, B, A-B: the symbol indicates the relative value at the input A, B, or the differen-
ce between the two inputs A-B
7 AUTO: the symbol indicates that the automatic change of scale device is enabled
8 °C/°F: key for selecting temperature reading in °C or °F
9 lx/fcd: key for selecting reading in lx=lux or fcd=footcandle
10 Data reset: the key erases the memory of the maximum, minimum and Q energy
values and the integration time
11 REC: when this key is pressed, the maximum, minimum and Q energy values and
the integration time in seconds, minutes, hours, are stored and updated
12 Itime: 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
13 MAN: 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 intervention 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
15 Q energy: when the key is pressed, followed by the
S
and Gkeys, this sets the
threshold value above which the alarm intervenes
16 A: key for activating the display of input A
17 A-B: key for activating the display of the difference between inputs A and B
18 SUB D male 9-pole connector. The cable with electronics for the serial output
RS232C, code AD RS232C, may be coupled to this connector
19 Input B socket, DIN 8-pole connector
20 X10-8: multiplication factor for the chosen unit; this may be 10

21 lx: symbol indicating that the reading is in lux
22 E/m-2•s: symbol indicating that the reading is in µEinstein
23 fcd/m2: symbol indicating that the measurement is in footcandle m

24 °C: symbol indicating that the temperature measurement is in °C
25 °F: symbol indicating that the temperature measurement is in °F
26 Wm2: symbol indicating that the measurement is in Wm
2
27 Q energy: symbol indicating the quantity of energy in the integration time X
28 m: integration time in minutes
29 s: integration time in seconds
30 h: integration time in hours
31 ON/OFF: key for switching the instrument on or off
32 DATA CALL: key for calling and reading on the display the stored maximum, mini-
mum and Q values
33 AUTO: 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
35 B: key for activating the display of input B.

K
Key for switching the instrument on
and off. The instrument switches off
automatically about 8 minutes after
this key has been pressed, as it has
a built-in switch-off device. If any
key other than the ON/OFF key is
pressed, the instrument switches
off 8 minutes after the last key was
pressed.
For measuring ILLUMINANCE;
when this key is pressed the reading may be in the photometric unit
lux or foot candle if a photometric
probe is fitted in the instrument.
If a temperature probe of the TP870
series is fitted in the instrument, this
indicates the temperature measured by the probe. The key may be
pressed alternately to give a reading in °C or °F.
When the key is pressed it erases
from the memory and resets the
maximum, minimum and integrated
Q energy values, then resets the
count of the time elapsed.
When the key is pressed the instrument stores and updates the maximum, minimum and integrated Q
energy values for the time elapsed,
recorded by the measurement probe fitted. The battery symbol fla-
shes.
During the RCD phase the AUTOPOWER-OFF function is disabled,
that is the instrument does not switch off automatically. To switch off,
press the ON/OFF key. If the stored
data are not reset they remain in
the memory until REC is pressed
again. When the key is pressed for
the first time it starts storing data in
the memory, the second time it stops data storage (the data stored so
far are not erased), the third time it
restarts storage and updates the
data.
When the key is pressed during
RECORD phase or at the end of Q
RECORD, before the DATA RESET
key is pressed, the display shows in
sequence the maximum value recorded by the probe, the minimum
value, the Q Energy value and finally
the current value. If the DATA
RESET key has been pressed, the
"Err" message appears on the
display, referring to the maximum,
minimum and Q Energy values.
When the AUTO key is pressed the
instrument chooses what scale to
operate on. Change of scale is
automatic.

Description
When the MAN key is pressed the
user chooses what scale to operate
on. There are 4 scales available,
except for temperature measurement where there are 2.
When this key is pressed the Q
Energy integration time that has
elapsed since the REC key was
pressed appears on the display in
seconds, minutes or hours.
To quit the routine, press the key
for the channel in which the reading
is being taken.
When this key is pressed followed
by the 1and 2keys, it sets the
maximum value of the Q Energy
threshold above which a buzzer
sounds to indicate that the set threshold has been reached. When
pressed for the second time it indicates the set threshold.
The value goes from 0 to 1999,
then continues with 103and 106. Q
Energy calculation begins when the
REC key is pressed and continues
until it is interrupted by pressing
REC again. When the set threshold
is exceeded the internal buzzer
sounds intermittently as long as the
instrument is in record mode.
NOTE: When setting the alarm
threshold, if the keys and 1(or
2
) are pressed simultaneously, this
makes the value on the display
advance faster. This may be useful

if a high value is to be set.
This key has two functions; in the
first, when Q is set, it increases the
value; the second function enables
the serial output. When the key is
pressed only once, the figure
shown on the display is sent to the
serial output. If the key is pressed
for more than three seconds the
continuous serial output is enabled;
this means that what is shown on
the display is sent continuously to
the serial output every 10 seconds.
To quit, press the 1key.
During Q setting the serial output is
disabled.
During setting of the maximum Q
threshold this key is used to
decrease the set value.
Key for selecting the input A probe,
if the probe is not inserted the "Err"
message appears.
Key for selecting the input B probe,
if the probe is not inserted the "Err"
message appears.
Key for displaying the difference in
value between inputs A and B; if no
probe is inserted, or if the probes
are of a different type, the message
E1 appears.
