REC

This function stores the minimum, maximum and average values of all displayed parameters. The clock shows the elapsed time in hours and minutes HH : MM since starting the REC function when displaying ‘Average’ and ‘Now’ values and gives a time stamp for when the ‘MIN’ and ‘MAX’ values occurred. The time stamp refers to the main first parameter on the display. If the real time has been set in the LOG/SET TIME menu then the clock displays the real time.

SAVE Mode

This function allows the capture of up to 8 screens which can be either waveforms or numerical data. Both waveform and harmonics screens are captured simultaneously in one memory location. Pressing the SAVE mode key brings up the following text on the screen:

SAVE RECOVER CLEAR

Use the

CLEAR. Repeat this process to select one of the SAVE locations from 1 to 8.

The whole screen is saved in the selected location and can be recovered at a later date - even after the instrument has been powered off. A second press of the SAVE key returns the instrument back to the normal mode of operation.

• Turn the rotary switch to LOG

• Select ENABLE LOG and change to ON

• Turn the rotary switch to either V, A, Hz, W, W3Ø

• Use

• Logging will commence approximately 5 seconds

later

The instrument will now log all displayed parameters to internal memory for 1 hour. The default interval between logged readings is 10 seconds.

Logging can be stopped at any time by turning the

rotary switch or pressing the display.

3.8.2 Displaying logged data

• Turn the rotary switch to LOG

• Select Display Data

• Select the parameter to be displayed.

• A chart display shows variations in the measured

value with time together with MIN, MAX, AVE values and the total logging period and logging interval.

3.9 Data Logging – Advanced

Selection of the rotary switch position ‘LOG’ brings up the following menu:

DISPLAY DATA

SELECT CHANGE

Two modes of data logging are available: either logging to an internal non-volatile memory or logging to an external PC, using the digital output lead.

INT Indicates internal logging

PC Indicates external (to a PC) logging

In PC mode, data is continually sent to the digital output and is not logged within the instrument. The Analyst logs all the parameters shown on the instrument display.

3.9.1 SET TIME

This gives access to the SET LOGGING TIMES menu, allowing the setting of current, start , stop times and the logging interval.

For ease of operation if the current time is changed, then the start is automatically reset to this time + 60 minutes, and the end time is set to the start time + 60 minutes. The minimum sample interval is 1 second, and the maximum sample 1 hour. A 24 hour clock is used. Start / Stop and logging intervals can be selected as required.

SET LOGGING TIMES

The maximum number of points that can be logged is:

10000 rdgs, 5000 sets of 2 or 2000 sets of 5

Page 19

The maximum logging duration is determined by the battery life (24hrs.) and the memory. Data being logged is an average over the sample period.

Using this information the maximum logging period can be calculated. For example, if logging the second Watts screen which shows 5 parameters, with a logging interval of 10 seconds, the maximum logging period would be:

2000 x 10 seconds = 5 hrs 33 mins.

3.9.2 ENABLE LOG

This enables the logging session. The low battery symbol flashes if there is insufficient battery life to complete the logging session defined in the SET TIME menu.

When internal logging is enabled the logging will commence within 5 seconds of selecting the

measurement screen with the rotary switch and key. All data displayed on the selected screen will be logged. ‘MEMORY’ flashes if there is insufficient memory to complete the logging session defined in the SET TIME menu. Once logging has commenced an on screen timer counts down the remaining logging period. Logging will terminate if the screen display is changed

through moving the rotary switch or pressing the key before the end of the logging session.

If PC logging is enabled, all measurements appearing on the instruments display will be logged to the PC. Logging will not terminate if the screen is changed.

This allows the user to download internal data to a PC running the WinLog program. The digital output lead must be connected from the digital output socket, on the front of the instrument, to the PC serial port. Within WinLog the port must be active and Download Log selected from the instrument option within the WinLog program.

On selection of SEND TO PC the text will flash until all data has been downloaded to the PC.

NOTE statements call attention to specific information.

The instrument has been designed to comply with IEC1010-2-032 Installation Category (Overvoltage Category) IV 600V Pollution degree 2 and UL 3111-1. The Analyst conforms with the EEC Low Voltage Directive 73/23/EEC and 93/68/EEC.

IEC 1010 is a safety standard which has the following features:

• Installation categories I to IV relate the maximum working voltage to overvoltage transients that can be expected in the measuring environment. For the Analyst instrument, 600V CAT IV, the maximum expected transients must not exceed 8kV peak.

• In a pollution degree 2 environment the internal design of the instrument can cope with transient conductivities due to condensation.

Death, serious injury, or fire hazard could result from improper connection of this instrument. Read and understand this manual before connecting this instrument. Follow all installation and operating instructions while using this instrument. Connection of this instrument must be performed in compliance with the National Electrical Code (ANSI/NFPA 70-2002) of USA and any additional safety requirements applicable to your installation. Installation, operation, and maintenance of this instrument must be performed by qualified personnel only. The National Electrical Code defines a qualified person as “one who has the skills and knowledge related to the construction and operation of the electrical equipment and installations, and who has received safety training on the hazards involved.” Qualified personnel who work on or near exposed energized electrical conductors must follow applicable safety related work practices and procedures including appropriate personal protective equipment in compliance with the Standard for Electrical Safety Requirements for Employee Workplaces (ANSI/NFPA 70E-2000) of USA and any additional workplace safety requirements applicable to your installation.

Users of this equipment and or their employees are reminded that Health and Safety Legislation

WARNING

requires them to carry out valid risk assessments of all electrical work, so as to identify potential sources of electrical danger and risk of electrical injury such as from inadvertent short circuits. Where the assessments show that the risk is significant, then the use of fused test leads constructed in accordance with the HSE guidance note GS38 ‘Electrical Test Equipment for use by Electricians’ is advised.

If the instrument is used in a manner not specified by the manufacturer, then the protection provided by the equipment may be impaired.

Maximum Safe Voltage

Current :- 600V MAXIMUM AC RMS or DC between

uninsulated conductor and ground and maximum frequency of 1kHz. This limitation applies to uninsulated conductors only.

Voltage:- 600V MAXIMUM AC RMS or DC between live conductor and ground. 600V MAXIMUM AC RMS or DC between V and COM terminals and a maximum frequency of 1kHz.

Safety precautions

The following safety precautions must be followed whenever any type of voltage or current connection is being made to the instrument.

• Wear proper Personal Protective Equipment,

including safety glasses and insulated gloves when making connections to power circuits.

• Hands, shoes and floor must be dry when making

any connection to a power line.

• Before each use, inspect all cables for breaks or

cracks in the insulation. Replace immediately if defective.

• Set the instrument power switch to Off.

• Before connecting to electric circuits to be

monitored, open their related circuit breakers or disconnects. DO NOT install any connection of the instrument to live power lines.

• Connections must be made to the instrument first,

then connect to the circuit to be monitored.

These safety precautions are repeated where appropriate throughout this manual.

• The instrument is intended for indoor use only.

• Do not attempt to take any measurement of current

or voltage higher than the maximum range of the instrument.

• The unit is not hermetically sealed and should NOT be brought into contact with surface water.

USE ONLY SUITABLY RATED VOLTAGE TEST LEADS TO IEC 1010-2-031. (600V CAT IV Pollution Degree 2).
