The Laurel Electronics L40 is a low-cost, universal meter for 65 user-selectable analog input signal types and ranges. These include DC voltage and current, AC RMS voltage and current, process signals (4-20 mA, 0-10V), thermocouple (10 types, °C or °F), RTD (6 types, °C or °F), thermistors (NTC or PTC), resistance (0-5k or 0-50k ohms), and potentiometer inputs. The same meter handles all of these signal types with no need for a plug-in signal conditioner board. The meter's universal power supply accepts voltages from 18 to 265V, AC or DC, so that power can be 24 DCV or AC power in any country. The meter conforms to the popular 1/8 DIN size standard and features four 0.56" (14.2 mm) high red LED digits. The display is user scalable for input types other than temperature.

The base L40, as shipped by Laurel, is set up so that a 400 Vac input reads 400. To change to another signal type or range, pry off the meter faceplate, push out the electronics, and place jumpers as illustrated in the manual. The jumper positions are well labeled, and the jumpers have a large, easy-to-grasp handle. Also make software selections using front panel keys. If you want Laurel or your distributor to set jumpers and do the front panel programming for you, order the FS option.

Extensive software features add flexibility to this low cost meter. Programmable features include five levels of display brightness, min and max capture, dual scaling selectable by an external control input, a deadband around 0 for AC measurements, a moving average digital filter, a "count by" function, hysteresis for alarm operation, a user-configurable fast access menu, and selectable password protection. Further flexibility is provided by 1 or 2 optional output boards, which can be added at any time.
