1.10 Configuration menu (cont.)

The instrument provides several functions to personalize the reading 

of the display values
• the ‘

Fixed Digits

’ (‘

FIX.d

’) allows to fix each digit to a fixed value. 

As an example, fix the least significant digit to a ‘0’ in order to block 

noisy fluctuations. To fix a digit, all digits to its right must be also 

fixed. Value ‘-’ means that the digit is not fixed.
• the ‘

Average filter

’ (‘

AVr

’) function allows to reduce reading oscil

-

lations due to noisy signals. It applies a recursive filter on the reading 

value. To activate the average filter set ‘

AVr

’ to ‘

on

’ and assign the fil

-

ter strength between ‘0.0’ and ‘99.9’. Higher values activate stronger 

filter. Stronger filters slow down the reading changes.
•  the  ‘

Steps

’  (‘

StEP

’)  function  allows  to  define  minimum  reading 

steps, which will be done in steps of 1, 2, 5, 10, 20 or 50 counts.

Example - selecting a step of 20 configures the reading to change in 

steps of 20 counts (‘1420’, ‘1440’, ‘1460’, ...).

• the ‘

Left Zero

’ (‘

LZEr

’) function lights all zeros to the left.

• the ‘

Memory of maximum

’ (‘

MAX

’) function displays the maximum 

reading value stored in memory. It also provides a way to reset the 

value. This parameter is eligible for configuration through the ‘

Fast 

access

’ menu 

(see section 1.10.6).

 • the ‘

Memory of minimum

’ (‘

MAX

’) function displays the minimum 

reading value stored in memory. It also provides a way to reset the 

value. This parameter is eligible for configuration through the ‘

Fast 

access

’ menu 

(see section 1.10.6).

• the ‘

Peak & hold

’ (‘

P.hLd

’) function visualizes and hold the maxi

-

mum reading. For test-break applications, where the meter always 

increases its value until 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 

time configured at the ‘

time

’ parameter.

   Time 0  

hold disabled (Off)

   Time 1 a 3999  seconds waiting
   Time 4000 

infinite hold

While ‘hold’ is active, the instrument alarms are still associated to 

the input signal, therefore still providing control to disconnect the 

application once the test has finished.
