VI Select test method
Please select test method based on real status, four statuses:
1 Use short(s) probe to measure: it is installed with the machine and
applicable to wide scope vibration measurement; it can acquire effective
response numerical value, as shown in the following illustration
2 Use long (L) probe to measurement: it is an accessory in a package,
mainly used in rather narrow or special object area, with quick response,
as shown in the following illustration
910
3 Use magnetic chuck to measure: it is an accessory in a package, mainly
used in plain area of iron objects, for instance, elevator etc. as shown in
the following illustration
4 Remove hardware probe to measure: used in plain object surface
measurement to acquire stable data, as shown in the following illustration.
VII Battery installation and check
Install battery:
Hold apparatus, press battery door with right thumb, open battery door from
the arrow-pointed direction, as shown in the following illustration.
11 12
2 Put 9V (G6F22 6F22) battery into battery holder correctly, aware of
battery polarity and then close battery holder door, as shown in the
following illustration.
VIII Power on and check battery status;
1 Press POWER key to power on.
As shown in the following illustration:
Press down
13 14
2 Press the key until LCD hold full display 1 second, stop pressing it to start
working with fault status being acceleration measurement mode, USB
failure to communicate and automatic power-off status; if LCD screen
displays symbol or , please replace battery timely as
shown in the following illustration.
Press POWER key to power off immediately.
IX Function operation instruction
1 Acceleration measurement:
1 Press key A to enter into acceleration measurement mode with fault
status being acceleration measurement mode m/s2 ,LCD screen shall
display aP; indicators of 10-10kHz and m/s2 are as follows:
2 Use probe to measure object according to the selected way and
measurement result shall display in data value display area of LCD
15 16
as shown in the following illustration:
2 Velocity measurement:
1 Press key V to enter into velocity measurement mode and LCD screen
shall display Vrms; indicators of 10-1kHz and cm/s are as follows:
2 Use probe to measure object according to the selected way and
measurement result shall display in data value display area of LCD as
shown in the following illustration:
3 Displacement measurement:
1 Press key D to enter into velocity measurement mode and LCD screen
shall display dp-p; indicators of 10-500Hz and mm are as follows:
