Number of measurements (standard setup with illumination)
– For R
INS
1 measurement – 25 s pause:
approx. 1100 measurements
– For R
LO
Auto polarity reversal / 1 
(1 measuring cycle) – 25 s pause:
approx. 1000 (Z502O) measurements
Battery test Symbolic display of rechargeable
battery voltage
Battery-saving circuit Display illumination can be switched off.
The test instrument is switched off
automatically after the last key opera-
tion. The user can select the desired
on-time.
Safety shutdown If supply voltage is too low, the instru-
ment is switched off, or cannot be
switched on.
Recharging socket Inserted rechargeable batteries can be
recharged directly by connecting a
charger to the recharging socket:
Z502R charger
Charging time Z502R charger: approx. 2 hours *
* Maximum charging time with fully depleted batteries.
A timer in the charger limits charging time to no more than 4 hours.
