I Overview

Designed with artificial polarization piezoelectric effect, UT313/UT315
portable vibration meter apply to the normal vibration measurement of
mechanical equipment, especially vibration measurement of the rotating and
reciprocating machinery, widely used in industrial measurement such as
Machine Manufacturing, electric power and metallurgy etc.

1. Battery symbol: indicates present remaining electricity. Four grades:
3 bars: sufficient electricity
2 bars: rather sufficient
1 bar: electricity will be
depleting, please replace
battery
Empty: electricity has
depleted, you have to replace
battery. The battery symbol
shall flicker.

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
