3 MAINTENANCE AND TROUBLESHOOTING

3.1 General instructions
Maintenance includes meeting the rules of operation and storage.
Repair of megohmmeter is only allowed at the manufacturer

’

s site or in special repair

agencies.

3.2 Possible failures and troubleshooting procedures
Possible failures and troubleshooting procedure are provided in Table 3.
Table 3 – Possible failures and troubleshooting procedures

Failure symptoms

Possible cause

Troubleshooting procedure

Instrument fails to

switch on

Storage battery (battery) is

discharged

Check the storage battery

(battery) voltage, charge (see

item 2.2.2) or replace (see item

2.4), if necessary.

On Е6-32 there is no

image with

illumination switched

Failure of display contrast setting

for this temperature

Set the required display contrast

(see item 3.2.1).

Storage battery does

not charge

Failure of power unit or storage

battery

Check battery charger, if

necessary, replace storage

battery (see item 2.4)

The instrument does

not respond to

buttons pressing

Microprocessor failure

Switch off the instrument for 5

seconds and switch it on again.

Disconnect and then connect

the storage battery, if necessary

(see item 2.4).

3.2.1 Megohmmeter allows to change image contrast on the display without entering

the menu. For this press button

when the instrument is switched off, hold it and switch

the instrument on. Use buttons

and

to increase and decrease the contrast,

respectively. To finish the contrast setting press button
