## Description

Full description not available

## Features

- Small size, easy to carry, responsive panel output. There are corresponding buttons for input and output of V, mV, mA and Ω, which can be transferred directly without combination buttons, the operation is very easy.
- Built-in single fast acting fuse can prevent most instrument damage caused by incorrect insertion of city voltage above 110V.
- AD, AD, reference voltage, operational amplifier and other important chips are all of high precision, high temperature stability, intended to improve the temperature stability and long-term aging performance of the instrument.
- The sensitivity of the thermal resistance and the resistance output to the external actuation current is reduced in the circuit structure. Increased output accuracy. It is suitable for the constant current and non-constant current of the external actuation current, which expands the usable range of the instrument.
- Quick response key without delay. The functions of the LB02 cover most of the functions required for maintenance of APIs, DCS, ESD, archived instruments, control valves, frequency converters, etc., with high accuracy and long-term stability.

## Questions & Answers

**Q: Is this the meter I would need to test thermocouples and also to mimic thermocouple signals to test the display unit?**
A: No, this device won’t measure or provide low level millivolt signals.

**Q: Does the unit have a user defined variable 0-10 vdc and 4-20mA output feature**
A: It sure does. Both have a variable output which you can adjust in 0.01 / 0.1 / 1.0 steps.

**Q: how is the unit powered? is it a rechargeable battery powered by usb or batteries, or does it need to be plugged in while in use?**
A: The unit has its own power pack, which are charged via USB port. 
I’ve not used it while charging, but battery lasts a long time
