The CL3013 is a reference standard with integrated three-phase current/voltage source. It's used for meter development, in laboratories, power companies or wherever you need a stabil current- and voltage output together with accurate measurements. The accuracy of the reference standard is class 0.05. Performed can be for example
The portable reference standard and calibrator RS350 is especially designed for the needs of metering engineers for on-site testing with high precision. The equipment offers highest functionality together with excellent menu guided operation through a 8” Tablet PC. It’s the perfect instrument to reduce technical- and non-technical losses.
What can I do with this instrument?
Accuracy Tests for Energy Meters
accuracy test screen
The RS350 can perform error measurement for maximum 3 energy meters at time. The last five individual errors are shown on the tablet together with average error and standard deviation. The instrument can also detect the meter constant, if the meter is not proper marked. The tablet gives full information for the testing time, remaining time and shows a progress bar. Instrument transformer ratios can be easy applied.
doing five accuracy tests in 27 seconds
Energy Register Tests
test of active, reactive and apparent registers in parallel
Register tests are necessary to verify that the energy supplied to the meter is matching with the internal register or counter. The RS350 can perform this tests on site.
Demand Register Tests
Demand Testing over 3 minutes
The RS350 can check demand registersover a defined time for up to 3 meters in parallel.
Instrument Transformer Testing
error test for current transformers
The RS350 can perform various instrument transformer tests. Current transformers can be tested for ratio, phase displacement and burden.
Real Time Measurement
display of all available parameters
The RS350 real time measurement display shows all 51 electrically relevant parameters on one screen. The instrument shows THD & Crest Factor for each phase in voltage & current. It has an easy application of Instrument transformer (IT) ratios for comparison purpose. Supported are many measurement modes, e.g. 1Ph 2W, 3Ph 3W, 3Ph 4W, in active, reactive & apparent mode, (total & fundamental). The Apparent power definition is switchable between arithmetical- or trigonometric calculation.
Long Time Measurement
long time measurement, graph view for reactive power
The RS350 can record all basic measurement values in cyclic time intervals. The intervals can be set between 1 to 99 seconds. The tablet can store 36,000 records (10 hours with 1 second interval time). The results can be displayed in table- or graphical format. It’s also possible to export the data to a comma separated values file (CSV). The record interval and integration time can be controlled by a start/stop timer.
Waveform Analysis
Waveforms for voltages and currents
The RS350 can flexible selected display the actual voltage- and current waveforms for maximum 6 channels in parallel, either in one graph or in one graph per phase. All waves can be saved. To capture suspicious events the RS350 has a HOLD function. The RS350 can also show the waveforms of active- and reactive power.
The RS350 can perform the analysis for harmonic content in voltage & current circuits up to 63rd order. All harmonics are displayed simultaneously on one screen in graphical or table format. All 6 channels can be stored together. It’s possible to select the harmonics in percent of the fundamental wave or as total RMS value. Power harmonics are displayed by phase.
Wiring Check

The RS350 helps you to debug complex wiring problems.
Vectorial display along with relevant electrical parameters
The automatic site analysis function of the RS350 checks the essential parameters versus predefined limits and makes wiring checks for the meter tester easier. Indicated with PASS/FAIL information are:
Presence of voltages & currents
Direction of currents
Balancing of phase voltages & currents
Phase symmetry
Phase sequence of voltage & current circuits
THD in voltage & current circuits
The limits can be set as per utility rules and regulations.
Wiring Simulator
Wiring Simulator
The calibrator RS350 has a integrated wiring simulator. The simulator can be used for analysis and for training purpose. It can either read the actual values or simulation values. It’s written in HTML/Javascript and supports most browsers. Take a look herefor full screen mode. All grey circles are interactive. It is possible to read and analyse the actual RS350 values. The interesting part is the financial loss due to irregular wiring at the right bottom.
Meter Testing Workflow
workflow procedure, here: check the seals
The workflow for the meter tester can be defined by the utility. It allows to create systematic meter test sequences. Once the structure is defined, all meter testers will report with the same testing content and nothing will be forgotten. The RS350 guides the user trough all test steps. The test sequence can include:
recording site data
verification of proper sealing
taking of photos
accuracy tests
record of the GPS location
Signature of witness
Report generation
You can share the reports by email, Whatsapp, Wechat or to whatever service is available on your tablet/phone.
Database
RS350 database
The RS350 has an internal database for all saved data. The pdf-reports are generated from the database. Individually imported and exported for synchronisation can be:
customer information
meter types
site information
meter test workflows
All test data can be uploaded to a common PC database working under our Electric Measurement Studio platform (EMS5).

Clamp-On CT, 100 A, neutral
The RS350 can measure the current in Neutral together with the phase currents. For Neutral current measurement an additional current clamp is needed. The specifications are the same as for the 100 A clamps.
Extension Box for 3 Scanning Heads
extension box for 3 scanning heads
The functionality of the RS350 hardware can be enhanced to use 3 scanning heads in parallel. For this purpose we have an extension box together with a connection cable to the RS350.
Additional Scanning Head
The basic set of the calibrator RS350 includes one scanning head. Sometimes it’s useful to check the accuracy of two or three energy meters in parallel. The hardware is supporting maximum 3 scanning heads. The additional scanning heads are delivered with fixing devices. Please note that the extension box is needed when using more than one scanning head. The specifications are the same as for the original delivered head.
Wireless Scanning Head
wireless scanning head
This scanning head can be used for detection of metrological LED pulse outputs for static electronic meters together with CLOU portable meter test equipment RS350. The TP-17 Wireless scanning head is based on the Nordic nRF24L01+, highly integrated, ultra low power (ULP) 2 Mbps RF transceiver for the 2.4 GHz ISM (Industrial, Scientific and Medical) band. It includes the Enhanced ShockBurst™ hardware protocol accelerator for a high-speed SPI interface. The no. of TP-17 Wireless scanning heads working in parallel is not limited.
The scanning system consists of
Scanning head TP-17 wireless 2.4 GHz transmitter, fixed at the energy meter
Fixing device TP-GS 2 – fastening to meter by two side-plates, can be moved up and down along the meter – can be used for rectangle- or round meters – adjustable width from 35 to 180 mm – provides magnetic adhesion to scanning probes – provides mechanical adhesion to scanning probes – probes can be moved left/right freely – made of insulation material, which ensures safety and portability

Start/Stop Switch
start/stop switch
This switch is connected to the pulse input socket of the RS350. It is used to test electromechanical meters under low load conditions. A scanning head needs about 2 full rotations of the meter disk for adjustment. With the Start-Stop switch you can monitor the mark on the disk. When it is in front, you press the button for starting the measurement. Once the mark arrives again at the front, press the button and see the error result.
