When the MAN key is pressed the user chooses what scale to operate on. There are 4 scales available, except for temperature measure- ment where there are 2.

When this key is pressed the Q

m

Energy integration time that has

h

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.

 

MAX - Q

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 thre-

 

shold has been reached. When

 

pressed for the second time it indi-

 

cates the set threshold.

 

 

The value goes from 0 to 1999,

 

then continues with 103 and 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,2

if the keys

 

and 1(or

 

) are pressed simultaneously, this

 

makes the value on the display

 

advance faster. This may be useful
