High overrange visual warning limit value

Display:

HIGH dISP

Range:

Any display value or

OFF

Default Value:

OFF

High overrange limit value - the display can be set to show an overrange message if the display
value rises above the

HIGH dISP

setting. For example if

HIGH dISP

is set to

1000

then once

the display reading rises above

1000

the message

-or-

will flash on and off or the display value

will flash on and off instead of the normal display units (see

dISP

function

7.59

). This message

can be used to alert operators to the presence of an input which is above the high limit. If this
function is not required it should be set to

OFF

by pressing the

^

and

v

buttons simultaneously

at this function.

Note: this function operates on frequency/rate display only.

7.59

Display visual warning flashing mode

Display:

dISP

Range:

FLSH

or

-or-

Default Value:

FLSH

Display overrange warning flashing mode - this function is used in conjunction with the

Lo dISP

and

HIGH dISP

functions. The

dISP

function can be set to

FLSH

or

-or-

. If the display

warning value set at the

Lo dISP

or

HIGH dISP

function is exceeded and the

dISP

function

is set to

FLSH

then the display value will flash on and off every second as a visual warning. If the

display warning value set at the

Lo dISP

or

HIGH dISP

function is exceeded and the

dISP

function is set to

-or-

then the

-or-

message will flash on and off once a second as a visual

warning. The warning flashes will cease and the normal display value will be seen when the value
displayed is higher than the low limit and lower than the high limit.

Note: this function operates on frequency/rate display only.

SET terminal input function

Display:

S.INP

Range:

Lo

or

Default Value:

hiGh

Sets, in conjunction with the SET terminal input, the count up/down operation of the totaliser.
The totaliser may be made to count up or count down via this function and if required made to
toggle between up and down count mode using an external contact closure between SET and GND
terminals. The

S.INP

function and the SET terminal input connection may be used in one of the

modes shown in the table below.
