Its high-precision, fully automatic full-signal output function provides a cost-effective calibration solution for measurement signals.
The MMB is an ideal handheld high-precision signal source for industrial sites, offering convenient on-site calibration methods.
Powered by a power adapter in production lines or experimental setups, the MMB serves as a core component of Automated Test Equipment (ATE). It features infrared isolated communication and significantly improves production efficiency.
Features:
- High Precision: Basic DC voltage output accuracy of ±0.02%;
- Full-Signal Output: Capable of outputting various industrial signals including voltage, mV, resistance, mA source, mA sink, 24V loop power supply, pulse, switch quantity, as well as thermal resistance, thermocouple and other thermal signals;
- Common Value Storage: Built-in FRAM memory supports storage and recall of 64 groups of output data;
- Dual Power Supply: Can be powered by batteries or an AC/DC power adapter;
- Infrared Communication: Two-way communication with a computer via an infrared isolated communication converter;
- Cold Junction Compensation: Automatically compensates for the cold junction temperature of thermocouple signals to directly simulate real thermocouple signals.
The MMB Multimeter Companion is a battery-powered or externally AC/DC power adapter-powered handheld high-precision signal source, which can output various specifications of industrial signals. Please refer to the following table: "Summary of Output Functions". In addition to the functions in Table 1, the MMB also has the following features and functions:
◆
Automatic Power Switching: Can work continuously by connecting an external AC/DC power adapter; when no external power is connected, it uses battery power (4 x 1.5V AA batteries).
◆
Battery Level Detection: Monitors battery power in real time and prompts the user of the current level.
◆
Save Common Outputs: Can store and retrieve up to 64 groups of common outputs.
◆
Multi-Information LCD Display: Displays various prompts including output value, signal type, power information, memory information, etc.; the upper and lower dual-line display facilitates setting and recalling common output values.
◆
Combination Keys: Output values can be entered not only via numeric keys, but also adjusted conveniently via direction keys.
◆
PC Suite Synchronization Software ※: Easily realize various functions such as instrument calibration, setting and output.
