These high-performance and low-price multimeter series consist of three models: the 6½-digit DMM 7461A, the 6½-digit DMM with temperature measurement  7461P and the 5½-digit DMM 7451A.
These multimeters realize high-speed sampling performance with selective sampling modes by adopting the newly developed A/D converter, supporting a variety of applications including digitization of pulse signals, logging measurement at certain intervals.
As another feature, the integration time can be set to any values. This enables correctly measuring the average values of pulsed current/voltage.
In addition,  the 7461P is capable of temperature measurement with a resolution of 
0.001 ℃ using a PT sensor.
Furthermore, these multimeters are provided with two channel DC voltage measurement (Bch 10 V range fixed), so that low cost measurement system architecture is available. 

By adopting the newly developed variable integration time A/D converter, the 7461A or 7461P and the 7451A realize the highest sampling rate of 20,000 readings per sec and 5,000 readings per sec with 3½-digit resolution respectively. The sampling interval can be set from 50 μs to 3,600 s for the 7461A or 7461P, and from 200 μs to 3,600 s for the 7451A, which allows high-speed digitization and data logging at precise measurement intervals.

The integration time can be set from 10 μs to 10 s for the 7461A or 7461P and from 100 μs to 10 s for the 7451A, which allows you to easily measure the average current of cellular phones or LCDs. The newly developed A/D converter of which integration time can be set to any values is based on the analog integration technique, so that it provides precise average measurement data, differently from the digital method using a discrete sampling.

Various types of measurements are supported by the built-in trigger functions such as the level trigger and the delta trigger.
Maximum sampling rate: 200 readings/s (from 5 ms)

In resistance measurement, measurement current may cause heat generation in a measured device and variation in its measured values. Low-power 2 WΩ/4 WΩ resistance measurement uses only 1/10 of the typical measurement current, minimizing the effect of thermal fluctuation.

Additionally,  the 7461 is capable of temperature measurement with a resolution of 0.001°C using a PT sensor. It is useful in various fields including automotive, home appliance, air-conditioning, energy control, medical and industrial equipment fields.
The 7461P signal ouptut can be selected from comparator output and digital output. In particular, digital signal output is useful for controlling opening and closing external devices, allowing easy system configuration.
