As noted last month, just because your workload is continuing to increase, doesn’t mean you need to be carrying around more tools to do it. You just need tools with more capabilities.
Agilent Technologies—the world’s premier measurement company—has you covered with its recently introduced U1233A Handheld Digital Multimeter.
Your meter should help you manage your most valuable asset: your time. The old paradigm has the meter taking readings while you watch. You have to be present when things happen. Under this arrangement, it can be difficult to multi-task. With the U1233A, you now have choices.
Starting with a simple freeze function, you can stop the meter from updating by pushing the blue button (Fig. 1). This allows you to view data when it’s convenient. Push and hold for one second to exit. Or, push momentarily to let the meter take another reading—again, when it’s convenient for YOU. With this “Trig Hold” capability, you control the trigger and the meter holds your reading.
Maybe you’re anticipating a step-change in your reading. You can automate the “trigger and hold” routine through the Auto Hold function of the blue button. Unlike other simple meters, the U1233A gives you a wide choice of steps, from 1 to 999 digits. You can choose to ignore those below the threshold and view only the significant ones. This is perfect for sorting similar electrical signals—like resistors, for example.
Perhaps you’re expecting or experiencing random changes in your measurements. This can be particularly confusing, as the digits rattle up and down. The bar graph provides some indication, but the U1233A has something better: Smoothing. This function displays the running average of past readings (your choice from 2 to 999 readings). Since you control how much smoothing is necessary to deal with the fluctuations at hand, you can make better sense of the measurements as the meter filters and “slows down” the rattling.

You may also want to assign the task of watching the meter to your PC—while you do something else. Download the free GUI Data Logger software from Agilent here. Then, connect the U1233A to your PC using the U1273A IR/USB cable. From your PC, you control the rate of entries of readings, from once a second (or ASAP) to once a day. Entries are time-stamped and you determine the number needed. This process can be scheduled via a real-time calendar and clock. Results can be reviewed at your convenience and exported to where the data are needed.
The PC connection also can be achieved remotely using a Bluetooth adapter U1177A. A 10-meter range gives you flexibility in situating your PC. The hopping frequency mode of the Bluetooth protocol helps make a robust connection and assures reliable results. For slowly changing signals, the PC combination provides easy choices for your time management and multi-tasking.

As you probably have noticed, today’s hydraulic systems are much smaller, run at more extreme temperatures and work harder than ever before. On top of those challenges, many hydraulic systems have to operate through a wide temperature range.
Finding the right hydraulic fluid can make a big difference in ensuring peak performance throughout extreme temperatures and conditions as well as helping to reduce downtime and extend drain intervals. Fortunately, just like our hydraulic systems, the hydraulic fluids we use in them have come a long way in terms of performance. Knowing what to look for is key to getting the right fluid for your system needs.
A number of important factors come into play when choosing the right hydraulic fluid. Of course, you want to make sure the fluid you choose meets OEM specifications and adheres to best practices. You also want to ensure you have a strict maintenance and service protocol to keep your equipment running at its best.

The importance of a high viscosity index…
One important characteristic to look for in a hydraulic fluid is the Viscosity Index (VI)—an important indicator of the oil’s ability to resist changes in viscosity due to temperature variations. The higher the VI, the less the oil’s viscosity will be affected by temperature changes.
For hydraulic equipment that is subject to a wide range of operating temperatures, high-VI fluids are essential to reduce internal pump leakage, eliminate sluggish operation and increase overall operating efficiency.

HYDREX keeps your operation running smoothly. It lasts up to three times (3X) longer and offers up to two times (2X) better wear protection than the leading hydraulic oil brand. HYDREX also resists oxidative breakdown—which prevents harmful sludge buildup. So, when you use the right fluids in conjunction with your preventive maintenance program, protecting your investment isn’t as daunting as you may think.
