1.3 Installation
1.3.1 Positioning the Instrument
Benchtop Use
The 5025 should always be positioned on a flat, firm surface. The instrument base is fitted
with four feet. The front feet have tilt legs to angle the instrument upwards for ergonomic
front panel operation.
•A 10 cm area of free space is recommended at the rear of the instrument.
•Do not obstruct the fan inlet on the rear of the instrument.
•Do not obstruct any exhaust outlets on the bottom of the instrument.
•Do not place objects or materials under the instrument.
Rack Mounting
A 19” rack mount option is also available. In this configuration mounting brackets replace the
carry handles.
Cleaning
When cleaning the 5011 use an alcohol-free wipe such as a ‘durable screenclean 50’.
Packaging
The 5011 is supplied in a carton with protective inserts. Retain the shipping box and internal
packaging for future use. If the unit is returned to Time Electronics for calibration, please use
this original packaging to avoid possible damage in transit.

2.4 Rotary Knob
The rotary knob is used to select ranges, settings and options. It is adjusted clockwise or
anti-clockwise to the required selection. The “Deviation” or “Option/Range” LEDs illuminate
to prompt usage of the rotary knob for the required operation. Ranges, options and settings
are activated by pressing the “OK” button after selection. Deviation is a mode that provides
percentage increase/decrease of an output and is active in real time.
The rotary knob is used for the following:
•Range selection (Resistance, DC V, DC I).
•Function settings (RTD or thermocouple type selection).
•Deviation mode.
•Settings options.
When illuminated the
rotary knob can be
used to deviate the
output.
When illuminated the rotary
knob can be used to scroll
through a list of selectable
options presented on the
display. Primarily used for
range selection.

•Instrument self-test and health check routine.
•Relay cleaning routine: A sequence of contacts ‘buzzing’.
•Front panel LEDs illuminate.
•Sounds the buzzer.
•Displays the model number and the firmware version number.
•Displays the communication type and setting.
•On completion of the start-up routine, the word “Ready” is shown on the display.

3.4 Using Deviation Mode DV%
This feature allows the output to be deviated in percentage steps. There are 3 options:
•Fine deviation: 0.001%
•Medium deviation: 0.01%
•Coarse deviation: 0.1%
The preference can be set in the Setup menu. See Setup Menu section.
1. To use Deviation mode start by pressing the “Function” button.
2. Then press the “DV%” button.
The right-hand side of the display then shows the deviation figure in + or - % terms.

Deviation mode is highlighted by illumination of the “Deviation” LED. This prompts the use of
the rotary knob.
3. To adjust the deviation, turn the rotary knob clockwise to increase, and anticlockwise to
decrease.
Note: It is not possible to adjust the deviation if the output setting is zero, since the deviation is a percentage of
value. The deviation will be displayed as zero percent in this case.
4. To turn off Deviation mode press the “Function” button followed by the “DEV” button.
