Description

1

Primary Parameters

Determine what parameter is going to be measured or
sourced.
The available options are: VOLTS, TC (thermocouple), RTD,
FREQ (frequency), PULSE, PRESSURE, mA, and mA 2W SIM.

2

Input/Output control

Switches between input mode (read), and output mode
(source).

3

Additional Settings

Available only for TC (thermocouple), and RTD measurements.
For TC this setting turns the CJC (Cold Junction Connection)
on and off.
For RTD measure [RTD IN], this setting sets the number of
wires used in the measurement (2-wire, 3-wire, or 4-wire)

4

Units

Shows what unit the measurement or source value is in.
Available options are for RTD and TC (°C or °F), and for FREQ
and PULSE (CPM, Hz, or KHz)

5

Sensor Types

Allow for measurements to be made for different types of RTDs
and TCs. All types are shown in the Specifications. Also, dis-
plays the amplitude of the pulse and frequency source, and
pressure units.

6

Numeric Displays

Display the numeric values of the signal being measured, or
sourced. An “OL” reading indicates an out of range or overload
condition.

7

Secondary Valve

Shows the base unit

Ω for RTD or mV for TC.

2.2 Menu Bar

The parameters on the display are controlled by the menu bar, which is located at the bottom
of the LCD. The function keys (F1, F2, and F3) are used to navigate through all the levels and
choices of the menu bar. Refer to the menu tree for a clarification on the layout of all the
levels.

The top level of the menu is the home menu. It can be accessed anytime by pressing the

In the input home menu the only active options are [MENU] and [LIGHT]. The [MENU] option
is used to enter the next level of the menu bar, the main menu. Press the corresponding
function key (F1) to enter the main menu. The [LIGHT] option is used to turn on the LCD
back light. Press the corresponding function key (F2) to turn on the back light.
