The 6 programs stored in the instrument are:
Program 1:
To manually enter calibration buffer values
Program 2:
To set upper and lower pH alarm limits
Program 3:
To set upper and lower mV alarm limits
Program 4:
To set upper and lower temperature alarm limits
Program 5:
To set end point and alert value pH alarms
Program 6:
To set RS232C Esc code (Default value is 16 decimal)
To stop or exit any program:
• press 0
• press PGM
Note:
the instrument must be in pH mode for program 1, 2 and 5.
Likewise the instrument must be in mV mode for program 3.
Otherwise a long beep will sound.
PROGRAM # 1 (HI 9017)
Setting of calibration buffer values other than those already memo-
rized (pH 4, 7 and 10), e.g. pH 6.86 (
HI7006
or
HI8006
) and
pH 9.18 (
HI7009
or
HI8009
):
• set the instrument to the pH mode
• press 1
• press PGM
At this stage, the left display shows "P1-1", and the
right display shows the measured pH value.
Dip the electrode and the temperature probe into
HI7006
or
HI8006
(pH6.86) buffer solution. Wait
for 30 seconds. Check the appropriate value for the
buffer at the measured buffer temperature from stan-
dard charts (see page 26).
