immediately collect the measurement’s data for in-the-field FFT
spectrum and phase analysis purposes.
•Bump Test Module – determine the natural frequencies of a
machine or a structure.
•Balancing Module – resolve single-plane, two-plane, static-
couple, and dynamic couple machinery balances with high
precision.
•Config Module - provides options that determine various
Microlog measurement setting defaults and system preferences.
In this manual, the Model 258 handheld device and each application
module are described in individual chapters.

Battery Operations
Power Adapter/Battery Charger
The Model 258's Power Adapter/Battery Charger (PSU-8) converts
AC power to DC power required by the Model 258. The Power
Adapter/Battery Charger kit includes a USB/Power Splitter Cable
(CA-38) that provides connections between the Model 258, the
Power Adapter/Battery Charger, and an external device’s USB
communications port.
You can connect the Power Adapter/Battery Charger with your Model
258 turned on or off. The Power Adapter/Battery Charger works
with AC power sources worldwide. However, verify that you have a
power cable designed for use in your country.
¾If you are running your instrument on AC power with
a battery installed, the AC Power Adapter/Battery
Charger charges the battery (if needed), then
maintains the battery's charge.
WARNING: The Power Adapter/Battery Charger should be
placed in a ventilated area (i.e., on a desktop) when used to
power the Model 258 or charge the battery. Do not use the
Power Adapter/Battery Charger in a poorly ventilated area,
as overheating may occur.
Install and Charge the Model 258 Battery
Prior to using the Model 258 for the first time, place the Lithium-Ion
battery pack (BP-8) in the device and charge the battery for a

minimum of six hours. The Model 258's battery charges when the
instrument is connected to its AC power adapter/battery charger.
¾You can operate the Model 258 from the external
power adapter/battery charger while waiting for the
battery to charge.
Once the battery is fully charged (or the Model 258 is connected to
the Power Adapter/Battery Charger), it is ready for operation.
Battery Life
Primary power for the Model 258 is provided by battery packs. The
battery packs operate for 6-8 hours in typical operating
environments, although the actual per-charge life can vary
depending on conditions, equipment options, and usage patterns.
¾The battery status displays in icon form in the top
right corner of the title bar.
IMPORTANT: Connect the Model 258 to its Power
Supply/Battery Charger whenever you do not intend to
resume operations in the immediate future.
How to Install the Battery Pack
WARNING: To ensure proper operation, ONLY use the
supplied battery pack.
To install the Lithium-Ion battery pack in your Model 258:
•Rotate the two screws ninety degrees on the battery cover
located on the underside of your device and lift the battery
cover away from the device.
•The main battery is removed by sliding the cell to the left and
lifting it out of the device.
•Insert the replacement lithium-ion battery in the battery
compartment and slide to the right to fit into place.
•Replace the battery cover and press down firmly on the cover
while re-securing the latches.
WARNING:
Do not expose the battery pack to temperatures in excess of
140°F (60°C).
Do not disassemble, incinerate, or short-circuit the battery
pack.
Danger of explosion if battery is incorrectly replaced.
Replace the battery only with the same or equivalent type
recommended by the manufacturer. Dispose of used
batteries according to the manufacturer’s instructions.
Do not open battery compartment in a hazardous area.

Replacing the Battery in an Active Model 258
If the instrument is running from battery power only, removing the
battery causes the Model 258 to shut off power to the LCD display
and to PC cards. The Model 258 may lose any data stored in RAM.
To avoid these problems, use the following procedure to replace the
battery pack in an active Model 258 running on battery power:
•Press the Power button to suspend the Model 258.
•Unlatch the battery and remove the pack.
•Replace with a fully charged battery pack and re-latch.
•Press the Power button.
How to Charge the Battery Pack
The Model 258's Lithium-Ion battery packs (BP-8) charge fully in 3-
5 hours in the instrument. To prevent overcharging, an internal
monitoring circuit shuts power off to the battery once it reaches full
capacity.
¾IMPORTANT - Charge the battery fully before using
the Model 258. Do not use the instrument during this
initial charge period.
The battery is charged using the power supply. After the initial
charge, you may use the Model 258 during subsequent chargings.
To charge a battery pack in the Model 258:
•Ensure the power source is plugged into a wall outlet.
•Insert the power source into the POWER connector at the top
of the Model 258.

no. CA-32) is for the Power/Trigger/USB connector.
CH1 provides input capabilities for X, Y, and Z signal input
channels, and for a trigger input.
¾Not all application modules support the Y and Z
inputs, or the trigger input.
CH2 provides input capabilities for Y signal input channel, and
for a trigger input.
¾Not all application modules support the Y input or the
trigger input.
Power/Trigger/USB Connector
To charge your Model 258’s batteries, connect the Power
Adapter/Battery Charger to the unit’s Power connector. When
power is being supplied to the unit, this connector is available for
USB communications with the host computer using the supplied the
splitter cable.
The maximum measurement range is +/- 40 V, while the minimum
full-scale range voltage available is 10 mV (peak). Inputs are
protected against higher voltage transients, however, sustained
over-voltage input levels must be avoided.
The Control Panel module’s ICP setting determines whether ICP
power is supplied to the transducer. Reference the How to Set
System Control Panel Settings section at the end of this chapter
for details.
The ICP supply is 24 Vdc (open circuit), 2.4 mA constant current.
