TSG 95 Pathfinder

Appendix C: User Service
Battery Hints
For optimal battery life and capacity, use the rechargeable NiCad
battery pack (Tektronix p/n 119-4488-00) in full charge/discharge
cycles. In other words, fully discharge the battery pack before re-
charging, and then charge the battery pack until fully charged,
approximately 16 hours. A new battery pack will take a few charge/
discharge cycles to reach full capacity.
WARNING.
Install or replace batteries only with the instrument
switched OFF and the AC adapter disconnected.
Replace the batteries only with standard AA batteries (1.2–1.5 V,
nominal), or with the optional rechargeable battery pack.
Setting the Auto Power Down (page 18) and Battery Type (page 19)
functions in the diagnostic menu also have an impact on battery life.
The battery types are disposable (Alkaline) or rechargeable (NiCad).
Setting the battery type changes the voltage thresholds for both the
BATTERY LOW display message and low-battery shutdown.
The BATTERY LOW Message
The warning “BATTERY LOW” will appear on the second line of
the TSG 95 display when the battery voltage drops below a predeter-
mined level. The level depends on the Battery Type set in the Diag-
nostic menu (see page 19). The TSG will operate for approximately
ten minutes after the message first appears. For best results, replace
or recharge the batteries when you first see this warning.
Low Battery Shutdown
To prevent erratic operation at very low power levels, the TSG 95
will shut itself down if the battery voltage drops below a second,
lower threshold that also depends on the Battery Type setting.
Low-battery shutdown can happen with little or no warning if, for
instance, the instrument has been left on by mistake with Auto Power
