Voltage at Terminals:

When not testing, the voltage displayed is the test voltage previously

selected. 

If there is an external voltage greater than 50 V present, this will be

displayed regardless of changes made to the test voltage. In this case the

instrument will not do a test, the 

TEST

button red LED and display

warning symbols will flash to warn of the hazard until the external voltage

becomes less than 50 V.

When testing, the voltage displayed is the voltage present at the test

terminals of the instrument.

If the test voltage is changed, by pressing either of the V

▲

and V

▼

buttons during a test, the new test voltage is displayed momentarily before

the voltage at the test terminals is displayed again.

Timer:

The timer shows minutes and seconds. At the start of a test the timer will

start from zero and at the end of a test it will stop. The duration of the last

test remains on the display until another test is started.

Digital Display:

The digital display shows the resistance or current being measured during

a test. The 

Ω

/ I

button toggles between the two. After a test the display

shows the last measurement made until V

buttons are

pressed.

Analogue display:

This simulates an analogue meter movement to give the user a better

"feel" for how a measurement is progressing. The analogue display shows

resistance only.

Battery Bar Graph:

This is a battery symbol on the LCD display comprising 4 pairs of

segments. The battery is monitored continuously when the instrument is

turned on the charge remaining in the battery is shown in the table below.

Fully charged battery

75% charged battery

50% charged battery

25% charged battery

Some testing still possible but battery may 

fail at any time

Symbol flashes when there is not enough 

charge to do a test and the instrument turns

itself off

When mains power is present the indicator shows the battery is being

charged by animating the segments of the bar graph.
