Introduction

The Fluke 1750 Power Recorder is a comprehensive yet easy to use system for power

quality investigations. The 1750 Power Recorder, referred to hereafter as simply “the

Recorder”, consists of a power recorder instrument, a wireless handheld Personal Digital

Assistant (PDA) for control and setup, and a powerful yet easy to use PC application,

Power Analyze. Four 400 A current probes are provided as standard equipment. A wide

range of ferro and Rogowski (flexible) type current probes are available from Fluke.

Key features of the 1750 Power Recorder are:

• No PC needed for setup

Using the included a wireless-enabled Personal Digital Assistant (PDA) as a controller,

you do not need a PC to configure the Recorder, troubleshoot connections, preview data,

or download the recorded data. The range of the PDA with the wireless link is about 15

meters (45 feet) from the Recorder.

• Simplified test lead connections to the power network

Differential inputs are not required due to internal referencing from phase channel to

phase channel. This means you simply connect a voltage probe to a conductor on each

phase that you want to record. On the current inputs, there is an identification resistor in

the connector that the Recorder uses to determine which probe is attached. The Recorder

then configures its measurement system appropriately for the model of current probe you

are using.

• Connection diagrams for the supported power network configurations (delta, Wye, and

others) appear on the handheld PDA controller. Once you make connections, you can

view live readings and a PHASOR diagram on the PDA to confirm the connections. If a

phase channel is wired incorrectly, you can swap the phase to another channel by

changing an internal Recorder software setting using the PDA, and then reconfirm correct

readings.

• Internal Uninterruptible Power Supply (UPS)

An internal NiMH (Nickel-Metal-Hydride) battery pack and charging system maintain

data capture continuity through power interruptions of 5 minutes or less.

• Automatic disturbance capture

The Recorder uses an automatic, self-learning threshold routine, which means you do not

have to set any event threshold limits before you start recording. You detect and display

power quality events (disturbances) using the Power Analyze software on a PC after the

event has been captured.
