Ram Meter Inc. - June 2021 Newsletter

June 11th, 2021:
We have just released our June 2021 Newsletter. Read on to see what we have in store this month.

It's June and that means it's summertime for those north of the equator! Which means it's winter in the southern hemisphere! Or if you're from the tropics then you likely won't notice much difference in temperature as much as how much precipitation. Whichever the case, we hope you enjoy the start of your next season. And there's no better way to enjoy it than with some great products from Ram Meter, Inc.! Check out what we have in store!

Laurel Electronics L40 Universal Input Digital Panel Meter

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.

Monarch Instruments F2A3X Signal Conditioner

The Monarch Instruments F2A3X Frequency to Analog module converts a frequency input signal into a proportional analog voltage (0-5 DCV) or current (4-20 DCmA) output. The output signal is electrically isolated from input signal and input power source effectively eliminating troublesome ground loops.

The input signal can be supplied from a Monarch sensor (measuring RPM for example) or any source of digital signal not exceeding 12 volts. The F2A3X is completely user programmable using the free downloadable PM Remote Software. A NIST certificate of calibration is also included.


  • Support for WiFI WPA, WPA2 Enterprise security protocol
  • Remote meter access via SerialNumber.accuenergy.io
  • Dual Ethernet RJ45 port with individual network configuration
  • Dual Ethernet ports and WiFi work simultaneously with different networks and data acquisition systems
  • COMtrade format for waveform capture
  • 8GB onboard memory with 1-second interval datalogging capabilities
  • Industry-leading 100ms and 40ms response rate via Modbus-TCP/IP protocol
  • Secure HTTPS data encryption to cloud server
  • SSL encrypted webserver plus TLS 1.2 compliance for industry-leading cybersecurity standard
  • Metering data backup log to avoid data loss during network downtime
  • Support industrial, utility and substation protocols IEC 61850, DNP 3.0 V2, Modbus-TCP/IP, SNMP, HTTP/HTTPs Post, FTP & SNTP

Amprobe Instruments GSD600 Gas Leak Detector

The Amprobe Instruments GSD600 Gas Leak Detector is a fast responding gas leak detector for methane and propane gas. The meter emits a frequency tone when gas is detected. The frequency of the beep coincides with the concentration of the gas. The LEDs display the level of gas present in an area or room. Pinpoint gas leaks for closed piping systems. Use the mute function in quiet work areas and utilize the LED displays. Or utilize the standard earphone jack for hearing the meter in loud environments.


  • Detects methane and propane gas
  • Quickly identifies and pinpoints gas leaks
  • Automatic calibration feature
  • 5 level LED alarm: >40, >80, >160, >320, and >640 ppm
  • Built-in earphone jack with mute function (earphone not included)
  • Flexible probe to access difficult measurement areas
  • Auto power off

Hioki PD3129-10 PHASE DETECTOR Phase Rotation Meter

The Hioki PD3129-10 is designed to safely detect the phase sequence in three-phase circuits for electrical installation and maintenance. Conventional metallic-contact phase detectors are constructed with a voltage cable with standard metallic clips, requiring the technician to clamp onto exposed metallic parts of the conductor and introducing the potential danger of electric shock accidents and short-circuit accidents caused by accidental contact between two metal points. Needless to say, ensuring safety in electrical work has been an increasingly important issue. A long-standing proponent of safety at the workplace, HIOKI released the PD3129 Non-Metallic Contact Phase Detector in 2004 and achieved the goal of ensuring a safe working environment for our users.

To enable more electricians to take advantage of our advanced technology, we have increased the range of vinyl-insulated wires that can be clipped with the non-metallic voltage clips to up to 500 mm2 in size, and extended the operating voltage range to 1000V AC. With the all-new Phase Detector 3129-10, safe phase sequence testing can now be conducted in even more environments where the previous non-metallic-contact phase detectors could never be safely applied.


  • CAT IV 600V and CAT III 1000V safe
  • Safe contact via the use of non-metallic clamp structure
  • Extra-large clips lets you clamp insulated wires of up to 40mm in diameter
  • Bright red LEDs let you detect phase orientation even in dark locations
  • Sharp buzzer gives audible recognition of phase detection
  • Line wire check function easily detects hot wires
  • Compact and lightweight - small enough to fit in the palm of your hand
  • Auto power-off function extends battery life
  • Low battery state indicated by blinking LED

Did you know that soil resistivity measures how much that soil conducts or resists electric current and can effect systems that pass current through the ground? It's important to understand these factors when selecting a ground resistance tester. Depending on what project you're undertaking and the testing method that works best for you may determine what you will need.
