1) Overview
Thank you for your purchase and use of our products! This chapter will introduce the
basic instrument performance, which is followed by notes of unpacking and installing.
1.1 Introduction to Instrument
SME1415 is a DC Resistance Meter with color LCD display and touch function. Its
accuracy of 0.01% is able to meet general resistance test requirements. Better
measurement result is obtained for temperature‐sensitive resistors by the adoption of
temperature compensation function. Statistic function has the capacity to make
statistic analysis of massive test data.
SME1415 is a powerful test tool for all kinds of resistor design, detection, quality
control and production. Its high test speed is applicable to the spot‐check machines
on production lines. With multiple output data and comparison mode, SME1415 can
meet different test requirements of different resistor manufacturers. The prominent
performance makes the test results come up to IEC and MIL standard.
1.2 Unpacking
Inspect the shipping container for damage after unpacking it. It is not recommended
to power on the instrument in the case of a damage container.
If the contents in the container do not conform to the packing list, notify us or your
dealer.
1.3 Power Connection
1) Power supply: 90V to 240V (dependable on the voltage setup on the rear panel).
2) Power supply frequencies: 50Hz and 60Hz
3) Power supply power range: ≤30VA
4) L (line wire), N (neutral wire) and E (earth ground wire) of the power supply input
socket should correspond to the power plug of the instrument.
5) The instrument has been specially designed for decreasing noise jamming
caused by the input in AC power terminal, but it is also recommended to use it in
the environment of low noise. If noises cannot be avoided, install a power source
filter please.
WARNING: To avoid injury to personnel and damage to the instrument resulting
from electric shock, do sure that the earth ground wire is safely grounded.

SME1415 Manual 8/118
1.4 Fuse
The fuse is a standard configuration, so use the included custom fuse please.
1.5 Environment
1) Do not store or use the instrument where it could be exposed to many dusts, great
vibration, direct sunshine and corrosive gas.
2) The instrument should operate under the temperature ranging from 0℃to 40℃,
relative humidity of no greater than 75%. For high accuracy, use the instrument in
the environment above mentioned.
3) For high accuracy, do not block the left air vent so as to ensure good ventilation.
4) The instrument has been specially designed for decreasing noise jamming caused
by the AC power input, but it is also recommended to use it in the environment of
low noise. If noise cannot be avoided, install a power filter please.
5) If the instrument will not be used for a long time, please place it in the original or a
similar packing box. The environment temperature should be kept in the range of
5℃to 40℃, and the relative humidity should not be greater than 85%. The box
should be located in an airy room where it could be exposed corrosive impurities
and direct sunlight.
6) Test leads on the instrument that are connected to DUTs should be kept away
from strong electromagnetic fields to avoid interference.
1.6 Use of Test Fixture
Only use the test fixture or cable made by our company, because the use of other test
fixtures or cables may result in incorrect measurement results. In addition, for good
contact of DUT and fixture, keep the test fixture or cable and pins of DUT clean.
Connect the test fixture or cable to HI and LO terminals on the instrument front panel.
Ensure the color and arrow conformity of the test fixture with that of sockets on
panels, thus to avoid abnormal measurement.
1.7 Warm‐
‐‐
‐up
1) For accurate measurement, the warm‐up time should not be less than 30 minutes.
2) Do not turn on or off the instrument frequently. This may cause internal data
confusion.
