7.1.5.2 Input window/modify a value
In the input window, the first line of the LCD always shows the heading, while the second line shows the
current setting.

Function name
-4,567 Unit
These modifications can only be made in Programming mode (refer to 7.1.2, “Operating modes” on page 43),
which means that a correct password (see 7.1.5.3, “Passwords” on page 46) must be entered. To move the
cursor from one decimal place to the next, use the

or

keys. To increase the value of the decimal place
just under the cursor by “1,” use the

key, and use

key to lower the number by 1. To change the minus
and plus sign, place the cursor in front of the first digit. To confirm and apply the change, press “Enter“. To
retain the current value, press “Esc”.
7.1.5.3 Passwords
Programming mode is password protected. The customer password allows all changes to be made that are
permissible for customers. This password can be changed when the device is first put into operation. Should
the password be changed, retain the new password in a safe place.
The UMC4 customer password in the device when delivered is 0002.
The service password allows for modification of all UMC4 functions. This password is not given to
customers.
For further information on customer passwords, see Section 7.2.2, “PASSWORD functional class” on page
53.
Display
The LCD display is designed for operation at temperatures ranging from − 20 °C to + 60 °C (-4° F to 140 °F)
without incurring any damage. However, at freezing or near-freezing temperatures, the display becomes
slow and readability of the measured values is reduced. At temperatures below − 10 °C (14 °F), only static
values (parameter settings) can be displayed. At temperatures exceeding 60 °C (140 °F), contrast decreases
substantially. When submitted to higher temperatures for long periods of time, the liquid crystals may dry
out.
