pressure system lead to the air outside, so as to prevent reverse suction of
auxiliary ink tank resulting from overpressure due to output of negative pressure
gauge.
The specific adjustment method is as follows:
1. Calculation of setting value for negative pressure gauge
A)
Differential mode:
threes values to be set for negative pressure gauge: Lo_1,
Hi_1 and P_2 with the unit Kpa, among which p_2=Lo_1=Hi_1-0.2.
For example, suppose Hi_1 = -50, -50-0.2=-50.2. then the setting value for p_2 and Lo_1
shall be -50.2. the final negative pressure value is between Lo_1 and Hi_1.
B)
EASY mode
: two values to be set for negative pressure gauge: P_1 and P_2
with the unit Kpa, among which p_2=P_1-0.2.
For example, suppose P_1 = -1.6, -1.6-0.2=-1.8. then the setting value for p_2 shall be -
1.8. the final negative pressure value is between P_1 and p_2.
2. Alteration method of setting value for negative pressure gauge
A) Differential mode
: Press “MODE” button to enter setting state and the secondary
display shows Lo_1 once and then the value of Lo_1. Adjust the value by pressing
▲
or
▼
button.
Continue to press “
MODE
” to enter setting state of
Hi_1
and the secondary display
shows Hi_1 once and then the value of
Hi_1
. Adjust the setting value of Hi_1 by
pressing
▲
or
▼
button.
Continue to press “
MODE
” to enter setting state of
P_2
and the secondary display
shows
P_2
once and then the value of
P_2
. Adjust the setting value of
P_2
by
pressing
▲
or
▼
button.
B) EASY mode
: Press “MODE” button to enter setting state and the secondary display
shows P_1 once and then the value of P_1. Adjust the value by pressing
▲
or
▼
button.
Continue to press “
MODE
” to enter setting state of P_2 and the secondary display
shows P_2 once and then the value of P_2. Adjust the setting value of P_2 by
pressing
▲
or
▼
button.
Note: when adjusting the setting value of pressure gauge, the interval for every setting
value shall not exceed 0.2.
Take the adjustment in A for example to show the setting process as follows:
