The instrument has two menus accessible to the user :
‘Conguraon menu’ (key SQ) (<)
‘Fast access’ menu (key UP) (5)
Conguraon menu
The ‘conguraon menu’ modies the conguraon parameters to
adapt the instrument to the applicaon needs. To access the ‘con-
guraon menu’ press for 1 second the SQ (<) key. This access can
be blocked by acvang the ‘Password’ (‘PASS’) funcon. While
operang the ‘conguraon menu’, the alarm status is ‘hold’ to the
status they had before accessing the menu, and the output and con-
trol modules remain in ‘error’ state. When leaving the ‘conguraon
menu’, the instrument applies a system reset, followed by a brief
disconnecon of the alarms and the output and control modules.
Funconality is then recovered.
For a detailed explanaon on the ‘conguraon menu’ see secon
1.12, and for a full view of the ‘conguraon menu’ structure see
secon 1.13.
‘Fast access’ menu
The ‘fast access’ menu is an operator congurable menu, providing
fast and direct access to the most usual funcons of the instrument
with a single key pad stroke. Press key UP (5) to access this menu.
See secon 1.12.5 for a list of funcons eligible for ‘fast access’ in
this instrument. The ‘Password’ (‘PASS’) funcon does not block ac-
cess to this menu. Accessing and modifying parameters in the ‘fast
access’ menu does not interfere with the normal funconality of the
instrument, and it does not generate any system reset when validat-
ing the changes.
Front key pad descripon
Key SQ (<) - press the SQ (<) key for 1 second to access the ‘con-
guraon menu’. Inside the menu, the SQ (<) key funcons as a
‘ENTER’ key. It selects and accesses the menu opon currently dis-
played. At menus with numerical value entries, it validates the num-
ber displayed.
Key UP (5) - the UP (5) key gives access to the ‘fast access’ menu.
Inside the menus, it moves vercally through the dierent menu op-
ons. At menus with numerical value entries, it modies the digit
selected by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Key LE (3) - inside the menus, the LE (3) key funcons as the ‘ES-
CAPE’ key. It leaves the selected menu, and eventually, will leave the
whole menu. When leaving the ‘conguraon menu’ with the LE (3)
key, the changed parameters are acvated. At menus with numeri-
cal value entries, the LE (3) key allows to select the acve digit. To
modify the value of the selected digit use the UP (5) key.
Menu ‘rollback’
Aer 30 seconds without interacon from the operator, the instru-
ment will rollback and leave the ‘conguraon menu’ or the ‘fast ac-
cess’ menu. All changes will be discarded.

To congure the inial set up of the instrument, select the measure
scale, the decimal point posion, and scale the reading.
Access the ‘Input’ (‘InP’) menu to select the measure scale. Opons
available are 0/600 Vac, 0/100 Vac, 0/10 Vac, 0/1 Vac, 0/100 mVac,
0/5 Aac and 0/1 Aac. Place the rear jumper according to the scale se-
lected (see secons 1.5 and 1.6).
Access the ‘Decimal point’ (‘dP’) menu to select the decimal point
posion. Move the decimal point by pressing the ‘LE’ (3) key.
Scale the reading at the ‘Scaling’ (‘ScAL’) menu. There are four pa-
rameters to congure :
• ‘Input low’ (‘ILo’) - minimum input signal, in Vac or Aac.
• ‘Display low’ (‘dLo’) - reading associated to the minimum input
signal.
• ‘Input high’ (‘IhI’) - maximum input signal, in Vac or Aac.
• ‘Display high’ (‘dhI’) - reading associated to the maximum input
signal.
The ‘Field correcon’ (‘F.cor’) funcons allows to correct the instru-
ment scaling parameters, when the instrument is being installed on
the eld, providing a fast and easy way to compensate oset signals.
To operate the ‘Field correcon’ (‘F.cor’) funcon for the oset cor-
recon, generate the minimum input signal and access the ‘Field
low’ (‘F.Lo’) funcon. Then the following sequence will start
• message with signal type (‘mA’ or ‘Vdc’)
• message ‘wait’ (‘WAIt’) in ash mode
• aer 5 seconds, message ‘ok’ (‘oK’) appears
• at this point, press key SQ (‘<‘)
• the menu returns to menu entry ‘Field Low’ (‘F.Lo’)
The instrument has read the input signal and automacally cong-
ures the ‘Input low’ (‘I.Lo’) for you.
Repeat the process generang the maximum input signal and access
the ‘Field high’ (‘F.hI’) menu. The instrument will read the input sig-
nal and automacally congure the ‘Input high’ (‘I.hI’) parameter to
match the signal read.
Applicaon - a current transformer provides a 0/5 Aac output signal
proporonal to the consumpon of an engine from 0 to 100.0 Aac.
At installaon, the operator detects that the reading at maximum
engine consumpon reads less than 100.0 Aac, although he knows it
is consuming 100.0 Aac. There is a reading mismatch due to the cur-
rent transformer characteriscs.
Congure the instrument for a measure scale of 0/5 Aac and scale
the reading for 0/100.0 Aac. When engine is consuming 100 Aac and
meter is reading less value, apply the ‘Field correcon’ / ‘F.Hi’ func-
on and the instrument will automacally correct the reading to
100.0 Aac.
If there is also oset error, the same applies when engine is stopped.
Reading should be 0.0 Aac. If it is not the case, apply the ‘Field correc-
on’ / ‘F.Lo’ funcon and the instrument will automacally correct
the reading to 0.0 Aac.

The ‘Alarms’ (‘ALr’) menu congures the independent acvaon of
up to 3 relay outputs (or transistor or SSR control), installed with the
R1 (or T1 or SSr) oponal modules (see secon 2.1). For outputs up
to 4 and 6 relays, see special modules R2, R4 and R6 at secon 2.6.
The alarm states are indicated in the front display with leds marked
as ‘1’, ‘2’ and ‘3’.
To congure an alarm, enter into the alarm menu (‘ALr1’, ‘ALr2’ or
‘ALr3’) and congure the following parameters :
• select ‘Acve’ (‘Act’) to ‘on’
• at ‘Alarm type’ (‘TypE’) select the alarm acng as a maximum
type alarm (‘MAX’) or a minimum type alarm (‘MIn’). The maxi-
mum type alarm (or minimum type alarm) acvates when the dis-
play value is higher (or lower) than the setpoint value.
• at ‘Setpoint’ (‘SEt’) enter the value for the alarm acvaon point.
This parameter is eligible for conguraon through the ‘Fast access’
menu (see secon 1.12.5).
• congure the hysteresis value at ‘Hysteresis’ (‘hySt’). The hys-
teresis applies to the deacvaon process of the alarm. The alarm
deacvates when the reading has passed the setpoint value plus
the hysteresis value. Hysteresis helps to avoid repeve switching
of the alarm relays, due to uctuang input signals around the set-
point.
• at ‘Acvaon delay’ (‘dEL.0’) congure the delay to apply before
alarm acvaon. The acvaon delay starts counng when the set-
point value is passed. Value from 0.0 to 99.9 seconds.
• at ‘Deacvaon delay’ (‘dEL.1’) congure the delay to apply
before alarm deacvaon. The deacvaon delay starts counng
when the setpoint value plus the hysteresis value, is passed. Value
from 0.0 to 99.9 seconds.
• to work with ‘windowed alarms’ (see graphical example below)
acvate ‘Setpoint 2’ (‘SEt2’) to ‘on’ and then congure the desired
second setpoint value. Second setpoint must always be higher in
value than the rst setpoint.
• the ‘Relay inverted’ (‘r.Inv’) parameter inverts the normal relay
connecons. When set to ‘on’ the relay will be acve when alarm is
inacve. For security applicaons where an inacve relay controls
the shutdown of the system.
• the ‘Locked alarm’ (‘A.Lck’) parameter disables the automac
deacvaon of the alarm. Alarm deacvaon must be performed
manually, by pressing the ‘LE’ front buon (see secon 1.12.8)

The instrument provides several funcons to personalize the reading
of the display values
• the ‘Fixed Digits’ (‘FIX.d’) allows to x each digit to a xed value.
As an example, x the least signicant digit to a ‘0’ in order to block
noisy uctuaons. To x a digit, all digits to its right must be also
xed. Value ‘-’ means that the digit is not xed.
• the ‘Average lter’ (‘AVr’) funcon allows to reduce reading oscil-
laons due to noisy signals. It applies a recursive lter on the reading
value. To acvate the average lter set ‘AVr’ to ‘on’ and assign the l-
ter strength between ‘0.0’ and ‘99.9’. Higher values acvate stronger
lter. Stronger lters slow down the reading changes.
• the ‘Steps’ (‘StEP’) funcon allows to dene minimum reading
steps, which will be done in steps of 1, 2, 5, 10, 20 or 50 counts.
Example - selecng a step of 20 congures the reading to change in
steps of 20 counts (‘1420’, ‘1440’, ‘1460’, ...).
• the ‘Le Zero’ (‘LZEr’) funcon lights all zeros to the le.
• the ‘Memory of maximum’ (‘MAX’) funcon displays the maximum
reading value stored in memory. It also provides a way to reset the
value. This parameter is eligible for conguraon through the ‘Fast
access’ menu (see secon 1.12.5).
• the ‘Memory of minimum’ (‘MAX’) funcon displays the minimum
reading value stored in memory. It also provides a way to reset the
value. This parameter is eligible for conguraon through the ‘Fast
access’ menu (see secon 1.12.5).
• the ‘Peak & hold’ (‘P.hLd’) funcon visualizes and hold the maxi-
mum reading. For test-break applicaons, where the meter always
increases its value unl the unit under test breaks and the signal falls
down. The meter maintains the maximum reading before the signal
fell down.
To free the ‘hold’ reading, press any of the front key pad or wait the
me congured at the ‘me’ parameter.
Time 0 hold disabled (O)
Time 1 a 3999 seconds waing

1.10 Conguraon menu (cont.)
The ‘On Power Up’ (‘on.Pu’) menu congures funcons to apply at
start-up. It applies only to instrument restart aer power loss. It does
not apply to instrument restart due to change in conguraon.
• parameter ‘Delay’ (‘dLAy’) assigns a waing me in seconds. The
instrument waits the congured me before starng normal func-
on. During this waing me, the display shows all decimal points
on in ash mode, all alarms are in ‘oFF’ state, there is no signal acqui-
sion and there is no communicaons or control being performed.
Aer the congured me is over, the instrument starts in normal
funcon. Delay value between 0 and 200 seconds.
Applicaon - the start-up process for an automaon system implies
that dierent parts of the system (engines, actuators, controllers, ...)
have dierent start-up mes. The ‘Delay’ funcon gives me to the
instrument to wait unl the slowest part of the system is fully func-
onal before execung acons on the system (signal reading, relay
