• Locking of measurement – press the START key and then press the LOCK key.
Release both keys. Measurement is in progress and current measured values are
displayed until the START key is again pressed and released.
Measuring process is indicated by (START) indicator.
4.1.2. HOLD function
When measurement is in progress then current measured values are displayed. By press and
release of the HOLD key the last measured result is displayed on display even if
measurement either ended or continues. The HOLD function is indicated by such way that
blinking of the (START) indicator changes to unremitting light.
HOLD function can be cancelled (measurement is still in progress) by press and release of the
HOLD key. The (START) indicator then blinks again.
4.2. Earth bond 200 mA - R
•
Make sure that tested equipment is deenergized – its mains voltage must be
disconnected before starting the measurement!
•
Do not connect any external voltage between R
test socket 1 or PE terminal 4.
•
If you are going to test equipment which can be charged to voltage > 25V (e.g.
filter capacitors), discharge it before test!
•
In case that external voltage is present on appliance under test, the
(PROTECT) indicator turns on and „Prot" message is displayed. Such status
is dangerous fault condition; disconnect equipment under test from the
REVEXplus immediately to avoid its damage!
4.2.1. Test lead resistance compensation
Compensation means that the test lead resistance is measured and then automatically
memorized and subtracted from all R
is thus displayed. The compensation constant remains in instrument's memory even if
the instrument is switched off. And so the lead compensation is valid until new
compensation is carried out.
