Operation Manual for DC Resistance Tester
1.6 Accuracy guarantee
（1）In order to ensure the accurate measurement of the instrument,
the heating time should be no less than 15 minutes.
（2）Do not frequent switching equipment, in order to avoid confusion
caused by internal data.
（3）Correct open circuit and short circuit operation.
（4）Short：When using 20mΩand 200mΩrange, should be first
cleared and then tested, and in other ranges generally do not
have to be cleared. See < user correction >.
（5）Rear panel ground terminal：When the resistance is too small or
too large, the test result may be beating, the user can put the
measured resistance into a metal shell, and then connect the
ground connection to the shell, it can reduce the beating. Note:
at any time the ground connection should not be in contact with
the test terminal.
（6）Do not open the test fixture too long time in 20mΩand 200mΩ
range. In the 20mΩand 200mΩrange, the output end of test
voltage is limited within 1V, if the test terminal open too long
time, when the switch range to high range, there will be digital
jumping phenomenon.
Chapter 2 Brief introduction
This series of DC resistance tester is designed for testing various
kinds of resistance, and has the function of comparison. When comparing
the state, can choose to display the resistance value or percentage
ratio, and can be judged by the set value of the resistance value is
high, low or good quality. At the same time, the machine is connected
with the mechanical processing equipment, and the sorting interface can
be connected with the mechanical processing equipment.
Application: coil, inductor, transformer, relay contact resistance,
resistors, fuse, connector cable resistance, PCB line resistance,
welding hole resistance, conductive film, metal detection etc.. The
temperature compensation function eliminates the influence of
temperature on the test, the temperature conversion function can
effectively measure the temperature of the device in the measurement.
CKT2516, CKT2515A, CKT2515B with statistical functions, can
effectively assess the production capacity, is conducive to the
production of the enterprise to control. CKT2515B, CKT2515A has a
temperature compensation function.
