“→” key: being pressed at the setting state, the data flicker bit will be right shifted for one
bit, the four bits will cycle in turn.
“．” Key: being pressed at the setting state, the decimal place will be right shifted for one
bit and cycles in return.
“Apk/ Hz/PF” key: being pressed at the measurement state, the lower right window of
display device will cyclically shift and display between “current”, “frequency” and “power
factor”.
“Sound proof” key: being pressed at the measurement state, the buzzer alarm will expire, if
the sorting result is qualified, the buzzer will not alarm; being pressed again, the buzzer will work
again; if the sorting result is qualified, the buzzer will give a hint.
2. Sorting setting procedures:
•First of all, the ultimate parameters of the product to be measured shall be determined.
• Press the “setting” key, the instrument will enter the setting state. The upper limited
parameters of current will be displayed on the current window and data of the first bit will flicker;
the “upper limit” indicator is on to indicate the upper limit parameters state of current being set.
Press the “↑” key to change the data of flicker bit to the number to be set; press the “→” key to
change the flicker bit, amend data of this bit and set the data of the four bits completely in turn
before pressing the “．” key to change the decimal place setting. After setting the upper limit
value of the current correctly and pressing the “setting” key for confirmation, the instrument will
save the upper limit value of current and enter the state of setting the lower limit value of the
current.
• Set the lower limit parameters state of the instrument, the lower limit parameters of current
will be displayed on the current window; data of the first bit will flicker and the lower limit
indicator will be on. The required parameters will be regulated by pressing the “↑”, “→” and “．”
key; press the “setting” key for confirmation, the instrument will save the lower limit value of
current and enter the state of setting the upper limit value of power.
•Set the upper limit parameters state of the instrument, the upper limit parameters will be
displayed on the power window; data of the first bit will flicker and the upper limit indicator will
be on. The required parameters will be regulated by pressing the “↑”, “→” and “．” key; press the
“setting” key for confirmation, the instrument will save the upper limit value of power and enter
the state of setting the lower limit value of power.
•Set the lower limit parameters state of the instrument, the lower limit parameters of power
will be displayed on the power window; data of the first bit will flicker and the lower limit
indicator will be on. The required parameters will be regulated by pressing the “↑”, “→” and “．”
key; press the “setting” key for confirmation, the instrument will save the lower limit value of
power and enter the state of setting the upper limit value of PF value.
•Set the upper limit parameters state of PF value of the instrument, the upper limit
parameters of power will be displayed on the power window; data of the first bit will flicker and
the upper limit indicator will be on. The required parameters will be regulated by pressing the “↑”,
“→” and “．” key; press the “setting” key for confirmation, the instrument will save the upper limit
value of power and enter the state of setting the lower limit value of PF value.
•Set the lower limit parameters state of PF value of the instrument, the lower limit
parameters of power will be displayed on the power window; data of the first bit will flicker and
the upper limit indicator will be on. The required parameters will be regulated by pressing the “↑”,
