INTRODUCTION
The LI25-2001 is an intrinsically safe and non-incendive loop-powered
meter approved for hazardous area locations. The LI25-1001 is a
general-purpose loop-powered meter for safe area applications. The
four front panel buttons make the setup and programming an easy task.
Five digits, bargraph, engineering units, and trend arrows provide a
clear and attractive presentation of the process.
The square root and programmable exponent functions allow for
conditioning of signals from non-linear transmitters without adding
external components to the system and the convenience of scaling
without a calibrated signal source make the LI25 Series the ideal choice
for process display applications.

INSTALLATION
There is no need to remove the meter from its case to
complete the installation, wiring, and setup of the meter.
Unpacking
Remove the meter from box. Inspect the packaging and
contents for damage. Report damages, if any, to the carrier.
If any part is missing or the meter malfunctions, please contact
your supplier or the factory for assistance.
Panel Mounting
• Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm
x 45 mm). Refer to Mounting Dimensions, page 33 for more details.
• Clearance: allow at least 4" (102 mm) behind the panel for wiring.
• Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Minimum steel/stainless steel panel thickness to maintain watertight
rating: 0.06" (1.5 mm).
Note: A steel or stainless steel panel rather than plastic is
recommended in cases where a watertight or dust-tight seal is
required between the meter and the panel.
• Remove the two mounting brackets provided with the meter (back-off
the two screws so that there is ¼" (6.4 mm) or less through the
bracket. Slide the bracket toward the front of the case and remove).
• Insert meter into the panel cutout.
• Install mounting brackets and tighten the screws against the panel.
To achieve a proper seal, tighten the mounting bracket screws
evenly until meter is snug to the panel along its short side. DO NOT
OVER TIGHTEN, as the rear of the panel may be damaged.

Connections
Signal connections are made to a four-terminal removable connector. This
section is only intended for the LI25-1001.
LI25-2001 installation must be performed in accordance with
Control Drawing QS301034-1 in order to meet agency approval
ratings.
Observe all safety regulations. Electrical wiring
should be performed in accordance with all agency
requirements and applicable national, state, and
local codes to prevent damage to the meter and
ensure personnel safety.

4-20 mA Input Connections
Input connections are made to a four-terminal connector labeled
S+|S-|B+|B-. The loop-powered backlight is an optional configuration and
requires a total maximum voltage drop of 5.7 V. The backlight is
recommended for dim lighting conditions and is enabled when wired as
shown in Figure 3. It may be bypassed if installed in bright lighting
conditions to reduce the maximum voltage drop to 2.0 V as shown in
Figure 4.

SETUP AND PROGRAMMING
• There is no need to recalibrate the meter for
milliamps when first received from the factory.
• The meter is factory calibrated for milliamps
prior to shipment. The calibration equipment
is certified to NIST standards.
Overview
There are no jumpers involved in the setup process of the meter.
Setup and programming is done through the front panel buttons.
After all connections have been completed and verified, apply power to
the loop.

Programming the Meter (prog)
It is very important to read the following information, before proceeding
to program the meter:
• There is no need to recalibrate the meter for milliamps when first
received from the factory.
• The meter is factory calibrated for milliamps prior to shipment.
The calibration equipment is certified to NIST standards.
• Use the Scale menu to enter scale parameters without applying a
live signal.
• Alternatively, use the Calibrate menu to apply a signal from a
calibrator or a 4-20 mA transmitter to calibrate the meter.
The Program menu contains the Calibrate and the Scale menus.
Inputs may be calibrated or scaled to any display within the range of the
meter.
prog SCAle CAL GrapH
Additional parameters, not needed for most applications, are
programmed with the Advanced features menu, see Advanced Features
Menu, page 25.
Error Message (Error)
An error message indicates that the calibration or scaling process was
not successful.
After the error message is displayed, the meter reverts to input 1,
allowing the appropriate input signals to be applied.
The error message might be caused by one of the following conditions:
1. Minimum input span requirements not maintained.
2. Input 1 signal inadvertently applied to calibrate input 2.
Minimum Input Span
The minimum input span is the minimum difference between input 1 and
input 2 signals required to complete the calibration or scaling of the
meter. The minimum span is 0.40 mA.

LI25 Series Loop-Powered Meters Instruction Manual
Scaling the Meter (sCalE)
The 4-20 mA input can be scaled to display the process in engineering
units.
A signal source is not needed to scale the meter; simply program the
inputs and corresponding display values.
