## Description

LB02 Resistance Current Voltmeter Signal Generator Source Process Calibrator 4-20mA/0-10V/mV LCD Display Update from LB01Note: this product is offered by top-tool store, if you need good qualtity and the best after-sales service, pls choose the top-tool store when you place the order, thanks!Description: This instrument can output/measurement the following signals: Current signal/Voltage signal/mV signal; 8 kinds of thermocouple(E,K,B,S,T,R,J,N) signal; Resistance signal; Thermal resistance(Pt100,Cu50)signal, containing 14 input,15 output, analog meter site can be read or the vast majority of quantities. V, mV, mA, Ω input and output has a corresponding button, call directly, no combination of keys, quick and easy operation. Small instrument, Rich functionality. Feature: Increase disposable fast blow fuse, to avoid false instrument damage caused by voltage 220V plug; In addition to having a conventional signal input and output functions, as well as resistance, PT100.Cu50 RTD, thermocouple eight kinds of input and output signals can be output, measuring negative temperature, very powerful; Thermal resistance, resistance to external excitation output current is reduced sensitivity. Increase the output and the measurement accuracy. For both constant and non-constant resistance measurement method, expanding the use of the instrument; All functions all use internal electronic switch; V. mV. mA. Resistance of the input and output has a corresponding button, directly call without advance menu, no combination of keys; Only two connector terminals, any level, regardless of the input and output all use these two terminals. Package includes: 1 x Calibrator 1 x Pair Test Pen 1 x USB Line 1 x Carrying Box 1 x User Manual

Review: Easy to use and works like a charm.
Review: Haven't used all the functions, but so far it works as expected. Started to build one from panel parts, soon found that I had double the cost and half the capability. Very nice

## Features

- Expect with the conventional signal input and output functions, as well as resistance, Pt100, Cu50 RTD, thermocouple input-output 8 kinds of signals, very powerful
- All functions all use internal electronic switch, and some other brands on the market, unlike DIP switch auxiliary products need to exclude the impact of the mechanical structure life, but also improves the ease of use
- Two connector terminals, any level, regardless of the input and output terminals of the full use of these two, no longer have to forget plug lead damage to the meter or equipment to worry about
- V, mV, mA, Ω input and output has a corresponding button, call directly, without advance menu selection, thermocouple, RTD input and output it is only after entering the function corresponding mV or Ω files left arrow or right arrow to select it, the operation is very simple, no combination of keys, quick and easy operation
- Segment LCD clear display and used multimeter or a calculator is the same. Large display area, visual area of 49*29mm. Low power consumption, maximum power consumption of less than 0.3mA. It will be less than 10mA, when the backlight is opened

### ⭐⭐ Review
*by D***Y on 30 March 2024*

Meter is extremely off on the low end of 4-20 mA. I have zero idea how it works with thermocouples, but somehow it works fine if you use copper/copper wire the whole way and was fairly accurate in all of the thermocouple types that I tried (K/S/B) Another drawback is being limited to Celsius from the temperature side. I’m sending mine back and going with a different option. The Memocal 2000 in the screenshots is pretty accurate and calibrated to ISO 17025 standards.
