GSAFETY WARNINGS

•Safety Warnings and Testing Precautions must be read and understood before the

instrument is used. They must be observed during use

•The circuit under test must be switched off, de-energised and isolated before test

connections are made.

•The test terminal panel and side recess panel must be kept in a dry, clean condition.

•Circuits must be discharged before disconnecting the test leads - Capacitive loads

can be lethal. See ‘Testing Precautions’.

•Circuit connections must not be touched during a test.

•In certain circumstances, break-down of the circuit under test may cause the

instrument to terminate the test in an uncontrolled manner, possibly causing a loss of

display and warning indications while the circuit remains energised. In this event, it is

important that the circuit is discharged and the instrument is turned off, before

touching any connections.

•Replacement fuses must be of the correct type and rating.

•The instrument should not be used if any part of it is damaged.

•Refer to ‘Testing Precautions’for further explanations and precautions.

The S1-5010 is an advanced insulation tester for all types of electrical equipment offering

measurement capability up to several T. The instrument performs automatic tests, enabling

consistent operation without operator input, stores results and can be operated from a PC. Flexible

power supply options and robust, portable construction allow the instrument to be used in a wide

variety of applications. It is particularly suitable for analyzing the insulation of large machines, HV

generators and cables. When turned On, voltage in excess of 50 volts across the + and - terminals

will be indicated on the display, together with the flashing HV symbols.

Switchable filtering allows stable readings to made when in the presence of high levels of 50 Hz or

60 Hz interference.

security code protected. It is also possible to set a general security code to prevent unauthorized use

of the instrument.

The S1-5010 can be powered from the main supply, or by the its own internal rechargeable battery

which provides for at least 8 hours of continuous testing. The battery symbol ,in the bottom

left of the display indicates battery capacity. Connecting power to the supply connector, or to the 12

volt connector in the side recess panel will automatically charge the battery whether the instrument

is switched ‘OO

ff’. A high level of internal isolation allows the S1-5010 to be used while the

battery is being recharged. An internal battery management system switches the instrument off after

ten minutes of inactivity. Test results and settings will not be lost when the instrument is switched off.

Test results are stored internally but the RS232 connection allows an external computer to receive

results in real time or to receive results previously stored.

Safe testing is achieved with a double insulated plastic case, double insulated test lead connectors,

a one second delayed start test button, high voltage warning symbols , flash on the display,

and the test terminal HV warning light flashes. A socket in the side recess panel provides a 5 volt

logic signal to drive an external warning light. Capacitive loads are automatically discharged at the

end of a test.

Beneath the display, four tactile keys normally control:-

- Electrical ‘noise’ Filter

- Contrast

- Back-light.

The S1-5010 can be powered by:

• Internal rechargeable battery which provides at least 8 hours of testing.

• Mains input of 95 volts to 280 volts 50/60 Hz.

• 12 - 15 Volts d.c or a.c.

General

The S1-5010 is fitted with a 12 volt, 7 Amp-hour sealed lead-acid battery. The maintenance free

battery will last for at least 5 years if kept charged and not subjected to prolonged high temperatures.

(Occasional exposure to +50° C will do little harm but a continuous temperature >40° may cause

irreparable damage). It is advisable to fully charge the battery before the instrument is put into service

for the first time. Charging is carried out by external a.c. mains supply, or by 12 V d.c. or a.c. supply.

To fully recharge the battery after 8 hours of use takes about 16 hours. The battery capacity display

symbol indicates the state of charge.

Mains supply re-charging

The application of a mains supply of 95 - 265 V a.c., 50 - 60 Hz powers the instrument, and charges

the battery. The S1-5010 will operate on a supply as low as 90 volts, but this will not fully charge the

battery. Charging is automatic as soon as the mains supply is connected to the IEC 320 connector in

the side recess panel. Confirm that the red indicator lamp is illuminated.

12 V supply re-charging

The application of an external 12 - 15 volt d.c or a.c. supply powers the instrument and charges the

battery at the same rate of charge as the mains input. It is possible to connect both mains and a 12

volt input simultaneously, but this will not charge the battery any faster. The socket accepts 12 -15 volt

d.c. (any polarity connection) or 12 - 15 volt a.c. A charging lead fitted with an automotive cigar lighter

plug for charging the battery from a vehicle is available (See ‘Accessories’). Charging is automatic

as soon as the 12 V supply is connected to the 12 V DIN socket. Confirm that the red indicator lamp

is illuminated.

12 V DIN socket

Caution:- Applying more than 15 V to this socket may overcharge the battery.

Battery Charging Notes

• Do not leave battery in a totally discharged state. Frequent charging to keep the battery ‘topped

up’ will maximise battery life.

• When charging the battery indoors, the area should be well ventilated.

• The battery should only be charged at temperatures in the range 0 °C to 40 °C.

• No harm will occur to the battery is kept on charge indefinitely.

• If the instrument is idle for long periods, recharge the battery for at least 24 hours every 6

months (more frequently if the storage temperature is >40 °C).
