Information on the calibration of newly purchased equipment and what it means to you.
Calibration and its certification comes in varying forms on new equipment and in this section, we will break it down into the three areas that we use to classify calibration state at the point of purchase.
Manufacturers Calibration Certificate
This is a calibration certificate offered by the manufacturer supplied with the tester. This is also known as an end-of-line certificate or manufacturer’s certificate. These certificates vary depending on the manufacturer and product. They will not have your company's name on them and don’t always show proven test results.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes complete with the manufacturer's calibration certificate. Please be aware that these certificates are generic and may also be time-lapsed.
If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.Manufacturers Certificate of Conformity
A manufacturer's certificate of conformity is not a calibration certificate. It is merely a statement that the equipment has been produced to operate within its intended application, it has no traceable certificate or constitutes any defined results for accuracy before leaving the manufacturing process.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.Personalised traceable calibration certificate from isswww
This is a calibration certificate created by us at ISS. This certificate is fully traceable to national and international standards. The certificate will show your company's details, tester information, proven test results and the equipment used to carry out the test. Nearly 90% of all calibrations we do are done in-house in one of our many fully equipped laboratories. You can add this service to your order on the product page before you checkout.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
We are on occasion able to offer FREE calibration on certain products at their point of sale (newly purchased equipment only) please look out for the following badge on the product's page to take advantage of this free offer.

A portable instrument that operates as a current and voltage source and a multi-purpose loop calibrator. High performance and simple operation make it suitable for R&D, service, process control engineers, and calibration technicians. As a versatile handheld calibrator, the source and measure capabilities with 0.02% accuracy mean the 1048 is a compact solution for most simulation and test applications.
A compact voltage, current, and process loop calibrator for engineering, manufacturing, test, and process control applications. This model combines digital accuracy with simple analogue control and is well suited to plant operations such as powering control loops.
• Source/measure voltage and current
• 3 source ranges: 0 to 22mA and 0 to 22V
• 3 measure ranges: 0 to 70mA and 0 to 50V
• Accuracy 0.02% of range
• Transmitter simulator/sink loop control
• Output steps and ramps
• Fine adjustment (inching)
• Battery powered 9V PP3, 20 hours typical use
• H142 x W78 x D50mm, weight 0.34kg
The 1048 combines the advantages of digital accuracy with analog control. Based on the popular functionality of the 1044 calibrator, the 1048 offers higher voltage and current across the three ranges, and improved accuracy. The additional features of transmitter simulation, sink loop control, output stepping and ramping, and incremental fine adjustment make the instrument ideal for use in the process industry.
The large, easy to read 4.5 digit LCD display shows the actual output, even when the connected load exceeds the specifications. This important feature eliminates the risk of large errors when connecting to unknown loads. The display also indicates if the battery becomes critically low.
In the source mode, voltage up to 22V and current up to 22mA may be generated in three ranges. When in current source mode the 1048 has a high 24V compliance voltage which is ideal for powering process loops.In the measurement mode, the range and function can be easily selected, with the measured input accurately shown on the display.
The step, ramp, and inching functions are simple operation, with no key press menus to learn, just switches and buttons. A multi-turn potentiometer controls the output, with up/down incrementing buttons for fine control. The output can be reversed (+/-) and zeroed at the flick of a switch. The automatic ramp function enables the user to choose either 5, 11, or 21 point calibration. Manual operation can be quickly restored by a single push of a button.
The 1048 is housed in a pocket sized ABS case, with carry case supplied as standard. Connections are by standard 4mm plugs or by simply clamping the wires under the terminals. A single 9V battery powers the unit or an external 12V DC power supply may be used which disconnects the internal battery.
Applications
Common use is to simulate a transducer or measure the current flow in a transducer loop. The 1048 can beused to check a 4 to 20mA system in either source or measure modes of operation, with the 24V compliance voltage powering the loop when current source mode is selected. In the source mode, the 1048 may be used to calibrate meters, thermocouple indicators, data loggers, for signal injection, semiconductor characterisation, or as a backing off source. In the measure mode, the 1048 may be used in the same way as a DMM, checking DC voltages and current over 3 ranges with excellent resolution and accuracy
