RS PRO IDM-8351 Dual Measurement Digital Multimeter (DMM)

RS PRO IDM-8351 offers unprecedented functionality plus the fastest measurement speed in its class. This instrument can measure 12 functions including AC/DC voltage, AC/DC current, AC+DC voltage/current, two-wired and four-wired resistance tester, continuity beeper, diode test, capacitance, frequency and temperature.

Its auxiliary functions include maximum/minimum values, dB, dBm, compare, reading hold and algorithms. RS PRO IDM-8351 features include a VFD display, maximum 120 000 counts, 0.012% basic DC voltage accuracy and USB/RS232C interface. When using the USB interface, the operator can select either USBCDC or USBTMC mode and, when selecting USBTMC, can control the multimeter in exactly the same way as with a GPIB interface.

What are the key features of the RS Pro IDM-8351?

• 120 000 counts, VFD display
• Dual measurement, dual display
• Basic precision of DC voltage 0.012%
• Selectable measurement speeds (slow, medium, fast)
• True RMS (AC, AC+DC) measurements
• 12 different measurement functions
• Many auxiliary functions
• Digital I/O (provides dual mode)
• Dimensions 265 x 107 x 302 mm
• Weight 2.9 kg approximately
• Standard RS-232C and USB Device Interface (Support USBCDC and USBTMC Modes)

Selectable measurement speeds
RS PRO IDM-8351 has the fastest measurement speed among the same category products and three selectable measurement speeds are available-slow/medium/fast. For instance, DC voltage can reach 320 readings per second on the fast mode, which can maximize the effectiveness of each measurement.

Convenient digital i/o function
The Digital I/O of RS PRO IDM-8351 provides two different modes which are general and self-definition. With the general mode, Digital I/O will output Hi Fail, Lo Fail, Pass and EOM (measurement results) based upon the results of the compare function and, furthermore, external trigger input is also provided. Under the selfdefinition mode, users can define output conditions for four pins (SET1∼SET4) to execute the external control.

Various measurement items and functionalities
RS PRO IDM-8351 provides various measurement items and functionalities compared with that of the products of the same category. There are twelve major measurement items of IDM8351, including AC voltage/current, DC voltage/current, AC+DC voltage/current, two-wired and four-wired resistance, temperature, frequency, diode and continuity beeper test, and even the capability of measuring capacitance.

Does the RS PRO IDM-8351 come with any warranty?

You have peace of mind as the RS Pro IDM-8351 Dual Measurement Multimeter is backed by 3 years of warranty.

What is included?

User manual, driver and software on CD, safety instruction sheet, test lead, power cord

Safety guidelines

When using any electrical test equipment it is advised that you refer to the user’s manual for proper working operating procedures and safety precautions in order to avoid potential safety hazards.


When using test leads or probes, keep your fingers behind the finger guards. Remove test lead from the meter before opening the battery door or meter case.
