Easy Recalibration

Recalibration is from the front panel or over the GPIB bus and

takes less than 20 minutes. The Calibration constants are held

in non-volatile memory so that no trimmer settings are

required. A 'cal key' provides calibration security.

EasyCal Calibration Software

A fully automatic calibration station can be configured using

Time Electronics PC based EasyCal software package. The

user’s Instrument/Equipment data base is set up along with a

calibration Procedure data base. Contained in the procedures

are sets of pre-defined calibration tests for each type of

instrument. When an instrument is ready for re-calibration the

system automatically recalls the information and the PC

automatically steps through the tests.. It sets up the calibrator

over the GPIB bus and prompts the user to select the required

range on the unit under test. On completion of the tests the

results (which are calculated using the spec figures held in the

Procedure) are written away to a Results database on the

PC’s hard disk. Calibration certificates to ISO 9000 or Namas

standard can be printed out on demand.

EasyCal software is an optional extra and comes ready to run

on a PC (Pentium + Windows 95 or better) . A GPIB interface

card and cable are also required in the PC – available from

Time Electronics or elsewhere.

Inventory Management

An optional add-on for EasyCal is Inventory Management.

This allows the user to maintain his instrument/equipment

database and keep track of where all the items are,

additionally printed reminders can be sent out when re-

calibrations are due. It is possible to keep records for a variety

of equipment on the database – not only that which is

calibrated by the system.

EasyCal Calibration

Software compatible

The 5022 is a multi-function calibrator, with AC/DC voltage

and current ranges plus resistance. It is suitable for calibration

of digital and analogue multi-meters and a variety of general

purpose measuring instruments.

General Purpose Interface Bus (GPIB)

The interface allows operation remotely from a PC or GPIB

controller. Simple high level programming commands provide

easy setting of range and value. Error condition readback is

also provided.

Offset and Deviation

Offset is used to back off initial zero values on the unit under

test and Deviation allows the output to

be changed

incrementally by

up

to +/-10%. The display then reads

directly in % error which simplifies the calibration process.

Error Detection and Self Test

The internal software constantly monitors the output and

displays and transmits (over the GPIB), error messages on

detection of a fault or overload condition. A built in self-test

program can also be run to check that key internal functions

are operating correctly and help with fault diagnosis.

Six Wave Forms from 15 Hz to 20 kHz in 5 Hz Steps

In addition to DC and AC Sine output, square, trapezoidal,

triangular, ramp up and down waveforms are available. This

enables checking the true 'RMS' performance of multi-meters,

linearity of chart recorders, and amplitude checks on

oscilloscopes.

Additionally, a slow sweep function allows

analogue meters to be checked for sticking of the pointer.

Safe High Voltage Operation

Emphasis has been placed on safety. Output voltages greater

than 50 volts can only be selected after pressing a safety

interlock key. On selection of an output greater than 40V, a

programmed 3 second delay, audio bleep and flashing led,

warns the user.
