Get fast, accurate, and repeatable measurements in electrically noisy environments with this low-resistance ohmmeter which features a difference meter that allows for repetitive measurements and easy comparison with an initial reference measurement. In addition. this ohmmeter is robust, handheld, and can be operated by non-technical users.
Get fast, accurate, and repeatable measurements in electrically noisy environments with this low-resistance ohmmeter which features a difference meter that allows for repetitive measurements and easy comparison with an initial reference measurement. In addition. this ohmmeter is robust, handheld, and can be operated by non-technical users.
To ensure the ohmmeter is always ready to test, this ohmmeter comes with AA rechargeable NiMH batteries that can be swapped for non-rechargeable standard AA alkaline batteries. In addition, this ohmmeter is ideal for outdoor use with an IP54 rating which ensures that neither rain nor dust will prevent testing.
Features
Test modes/options
The ohmmeter has three main test modes:
Normal resistance mode
Gives the most flexibility. The user can set any maximum test current range up to 2 A and the instrument will auto range to suit the measured resistance up to that value. Useful if the test piece has a limit to the current it can withstand. The user has full control of the instrument's test features which is suitable for many applications, as listed above.
Fast/long test leads mode
Only has one user option, which is manual/auto. ‘Manual' starts the test when the TEST button is pressed, ‘auto' starts the test automatically when the instrument detects continuity. In this mode, the instrument settings are optimized for speed and, if needed, the use of very long test leads. The test current is only in one direction for speed, 1 A and above, resistance is only displayed in mΩ. This test mode is ideal for many applications but is focused on applications where:
Inductive resistance mode
Tests with the test current set to 1 A to speed up the charge time. The test current will be auto ranged up as the inductance is charged. Additional convenience is added with a clever ‘auto stop' feature. The instrument will monitor the rate of change and automatically stop the test as soon as the result is stable.
