Calibrator RS350

RS350 calibrator with tablet

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

The RS350 can perform error measurement for maximum 3 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.

Real Time Measurement

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.

Meter Testing Workflow

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

Content of delivery

Calibrator and Tab

Reference Standard and Tablet PC
The calibrator RS350 has it’s own compartment inside of the transport case. The tablet is for transport safely stored in the case flap.
The actual tablet is a Lenovo TB3-850F. It has 1 GB RAM and 16 GB internal storage. Operation with battery is up to 8 hours.

Transport Case

The equipment is delivered in a trolley with wheels and handle for easy transportation. The trolley is designed in such way that you can leave the RS350 inside and only make the connections to the meter. The cables can remain connected to the RS350 during transport. This saves time and increases the efficiency of use. The suitcase dimensions are 483.5 mm x 474 mm x 237 mm. The weight with standard accessories is less than 12 kg.

Scanning Head

A wired scanning head belongs to the standard scope of delivery for the RS350. It can detect rotor marks for electromechanical meters and pulse diodes for electronic meters. LEDs with a wave-length of 400 – 1100 nm and with pulse frequencies up to 3 kHz can be detected.
The scanning head is delivered with a fixing device. The clamping width is 10 mm to 180 mm.

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.

Recalibration

The calibrators RS350 are leaving our factory with a traceable calibration certificate.
All metrological instruments need to be recalibrated regular. The recalibration period depends on country regulations. In most countries portable calibrators have a recalibration period of one year.
The recalibration can be done in any for this purpose accredited laboratory.
The general principle is to compare the calibrator pulses with the reference standard pulses. Connect the P-OUT to the pulse input and GND to the ground, calculate the meter constant for the actual load and verify the RS350 accuracy with the higher accurate standard.
RS350 meter constants
RS350 meter constants

The RS350 can also be adjusted locally at any metrological institute.

Connection to energy meters

This is only a short reference for most common meters. Make sure that you have read the RS350 operation manual with more examples.
Always follow your company safety guidelines. In addition it’s no mistake to take a look at our safety regulations.
