Introduction
We make a truly portable and highly reliable Universal Calibrator which can be used for many types of Process Control Instruments working on mV, mA, or resistance. Source & Sink facility is built-in. The Calibrator is designed to suit the Instrument Lab as well as field calibration. This can be used as a better tool for fault finding and confirmation of instrument/ Sensor reliability. Hence, it is very useful for Commissioning, Quality assurance, Routine Maintenance, and Troubleshooting.

Functional Specification –
Power ON– This switch powers the instrument with batteries/ eliminators when switched “ON”.
Select– Uni calibrator suppliers use a Rotary selector switch to select the required parameters mV/mA/Ohm/Temp
Mode– Source (Generation) or Sink ( Measurement) facility can be selected.
mV/mA coarse & fine adjustment– Both the potentiometers are Multi-Turn Helipots & used to get the exact value of mV/mA.
Ohm– Uni calibrator suppliers measure resistance in the range 0-1999.9 ohms (Calibrated for 0-500 ohm) in source & Sink Mode
RTD Simulation– pt 100 simulation directly in terms of Temp. is achieved by Multi-turn Helipot. You can select the Temp. for which Resistance output is required. Uni calibrator suppliers Read the value and then feed by using the READ/FEED SWITCH.
Terminals– Are provided for mV (Source/sink), mA Sink & Resistance / Pt100 (RTD)Source/sink.
Calibration Chart– With resp. to temp. suitable for Thermo-couples J,K,R,S& Pt100(RTD).
Battery Eliminator-(optional)This facility is provided in the Calibrator to suit the operation on 230V AC 50 hz+10%. As soon as you connect the Eliminator Socket, batteries get disconnected automatically & vice versa.
Battery Replacement- When “Low Bat” Indicates appears on DPM, the discharged batteries must be replaced, otherwise the accuracy will not be achieved. For replacing the battery remove the side bottom plate and then slide out the bottom plate on which the battery is firmly placed.
Uni cal– Can be calibrated easily. Remove the top plate. Potentiometer for mV, mA Source, mA Sink, Ohm/Temp are in sequence & easily accessible. Uni calibrator supplier refers to the Instruction Manual.
Applications –
- Uni calibrator suppliers are used for the calibration of Process Control Instruments and Systems for various industries such as Cement, Chemicals, Dyestuff, Plant, Drugs, Pharmaceuticals, Sugar, Paper, Glass, Food Industries, Steel, Synthetics, Auto, Air conditioning & Refrigeration.
- As a fault-finding tool.
- Uni calibrator suppliers have Quality Assurance tools for ISO 9000, and QS 2000 companies for Control of Inspection & Measurement.
