Section 1 Introduction

Your MDSi8 Series Benchtop Meter is ideal for laboratory use and applications
requiring portable temperature measurement. There are two basic models, a
single-channel and a ten-channel unit. The single-channel model features a
universal input that can be reconfigured by you for use with a thermocouple,
RTD or Voltage/Current signal. The ten-channel model is a dedicated input type
of either 10 thermocouples, RTDs, or Voltage/Current signals. These meters are
factory configured and calibrated. It is important that you read this manual and
additional manuals outlined in Section 6 completely and follow all safety
precautions in both manuals before operating your unit.

1.1 Precautions

• Follow all safety precautions and operating instructions outlined in this manual.

• Keep unit out of reach of children.

• Do not operate in flammable or explosive environments.

• Never operate with a power cord that is not properly rated for use with your unit.

• Remove and or disconnect main power cord before attempting any
maintenance or fuse replacement.

• Do not connect and/or operate this unit to a non-grounded, non-polarized
outlet or power source.

There are no user serviceable parts inside your unit. Attempting
to repair or service your unit may void your warranty.

This product is not designed nor recommended for medical
applications.

1.2 Safety Warnings and IEC Symbols

This device is marked with international safety and hazard symbols in
accordance with EN61010-1. It is important to read and follow all precautions
and instructions in this manual before operating or commissioning this device as
it contains important information relating to safety and EMC. Failure to follow
all safety precautions may result in injury and/or damage to your calibrator. Use
of this device in a manner not specified by the manufacturer may impair
protection devices and safety features provided by the unit.

3.11 Meter Setup and Programming

3.11.1 Factory Configuration

All models are factory configured and calibrated. Below is a description of how
your unit has been configured.

3.11.2 Single-Channel Models

Single-channel units are factory configured and calibrated for Type-K
thermocouple unless a different setup was requested when you ordered your
unit. Your unit can be reconfigured in the field to a different input type without
the need to recalibrate the meter. The procedure for changing the meters
programming can be found in the accompanying Manual M3355.

3.11.3 Ten-Channel Models

No configuration is required. Your unit has been manufactured, programmed
and calibrated for the input type you ordered by model number. Do not change
or reprogram the meter's input type or incorrect readings will occur.

4.1 Communication Option (Ethernet, RS232/485)

Your meter has been factory pre-wired and configured for ease of use with your
communication option. Connections are made on the rear panel.

4.1.1 Ethernet

The RJ45 connection on the back of the meter has been extended out to the rear
panel on your Benchtop Meter. Connection and use of the ethernet option is
outlined in Manual #M3629 that was included with your unit.

4.1.2 RS232/485

Your meter has been factory pre-wired and configured for ease of use with a
standard DB9 female connector on the rear panel. Page 6 of your
Communication Manual #M3397 shows how your rear panel connector has been
wired. Connections to your PC should be straight through wiring as shown
below.

Section 5 Maintenance

5.1 Calibration

This unit has been fine-tuned and factory calibrated to give optimum
performance over its full operating range. Refer to Manual #M3355 for
additional information on meter calibration and setup.

Remove all electrical connections and power before
attempting any maintenance or cleaning.

5.2 Cleaning

Lightly dampen a soft, clean cloth with a mild cleaning solution and gently clean
the Benchtop Meter.

5.3 Fuse Replacement

Disconnect all power from source before attempting fuse
replacement.

For continued protection against the risk of fire, replace fuses
with only the same size, type, rating and safety approvals
indicated here and on the rear panel of your unit.

All power line connections to your unit are fused. When
operating on single-phase power source such as 120 Vac in
the USA, the neutral line is also fused.
