Introduction The 1730 Energy Logger (the Logger or Product) is a compact device for energy surveys. With a built-in touch screen and USB flash drive support, it is very easy to configure, verify, and download measurement sessions without the need of a computer at the measurement location.
1730 Users Manual How to Contact Fluke Safety Information To contact Fluke, use one of these telephone numbers: A Warning identifies hazardous conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that can cause damage to the Product or the equipment under test.
Energy Logger Safety Information • Use Product-approved measurement category (CAT), voltage, and amperage rated accessories (probes, test leads, and adapters) for all measurements. • Do not use test leads if they are damaged. Examine the test leads for damaged insulation and measure a known voltage. • • Do not use the Product if it is damaged. The battery door must be closed and locked before you operate the Product. • Do not work alone. • Use this Product indoors only.
1730 Users Manual Table 1 is a list of symbols used on the Product or in this manual. Table 1. Symbols Symbol Description Symbol Description Risk of Danger. Important information. See manual.
Energy Logger Before You Start Before You Start Below is a list of the items included with your purchase. Carefully unpack and inspect each of the items: • 1730 Energy Logger • Power Supply • Voltage Test Lead, 3-phase + N • Dolphin Clip, Black • i1730-flex1500 Thin-Flexi Current Probe, 30.5 cm (12 in) quantity 3 • Color-coded Wire Clips • Power Cord (see Figure 1) • Set of 2 test leads with stackable plugs, 10 cm (3.9 in) • Set of 2 test leads with stackable plugs, 2 m (6.
1730 Users Manual Tilt Stand The power supply includes a tilt stand. When used, the tilt stand positions the display at a good angle for use on a tabletop surface. To use, attach the power supply to the Logger and open the tilt stand. Hanger Accessory The optional hanger accessory shown in Figure 2 is used to: • Hang the Logger with power supply attached (use two magnets) • Hang the Logger separately (use two magnets) • Hang the power supply separately (use one magnet) hcf058.eps Figure 2.
Energy Logger Storage Storage When not in use, keep the Logger in the protective storage bag/case. The bag/case has sufficient space for the Logger and all the accessories. If the Logger is stored for an extended period of time or is not in use for a long time, you should charge the battery at least once every six months. The power cord/measurement line cover slides to select the input source.
1730 Users Manual How to Charge Battery The Logger also operates on an internal rechargeable Lithium-ion battery. After you unpack and inspect the Logger, fully charge the battery before first use. Afterwards, charge the battery when the battery icon on the screen indicates that power is low. The battery automatically charges when the Logger is connected to the mains power. The Logger continues to charge when turned off and connected to mains power.
Energy Logger Accessories Accessories Table 2 is a list of the accessories that are available and sold separately for the Logger. The warranty on included accessories is 1 year. Table 2. Accessories Description Part Number Description Part Number i1730-flex 1500 Thin-Flexi Current Probe (single) 4345324 3PHVL-1730, Voltage Test Lead 3-phase + N 4344712 i1730-flex1500/3PK Set of three Thin-Flexi Current Probes 1500 A 30.
1730 Users Manual Voltage Test Leads Voltage test leads are four-core, flat, test leads that do not tangle and can be installed in tight spaces. On installations where the access to Neutral is out of reach with the threephase test lead, use the black test lead to extend the Neutral lead. The R-coil has many advantages over other types of current transformers: • It is not a closed loop.
Energy Logger Accessories Use the color clips for easy identification of the three current clamps. Apply the clips that are appropriate for your local wiring codes on both ends of the current clamp cable. See Figure 5. Kensington Lock A Kensington Security Slot (also called a K-Slot or Kensington lock) is part of a built-in anti-theft system. It is a small, metal-reinforced, oval hole found on the right side of the Logger (see item 6 in Table 3). It is used for attaching a lock-and-cable apparatus.

Energy Logger Navigation and User Interface Power ON/OFF The Logger has several options for power: mains, measurement line, and battery. The front panel LED shows the status. See Table 5 for more information. Mains Power Source 1. Attach the power supply to the Logger or use the dc power cord to connect the power supply to the Logger. 2. Move the slide-cover on the power supply to access the mains socket and connect the power cord into the Logger.
1730 Users Manual Power from Battery The Logger can operate on battery power without a connection to the power supply or dc power cord. Push . The Logger turns on and is ready to use in <30 seconds. The battery symbol in the status bar and the power LED indicate the battery status. Table 5.
Energy Logger Navigation and User Interface Touch Screen Calibration The touch screen enables you to interact directly with what is on the display.
