Appendix 9 Frequently Asked Questions

Here are some common questions and answers about the HiLogger.

Installation and Settings

Question
Can the HiLogger be installed at
an angle? Can it be mounted on a
wall?
How to measure the temperature
of an object having applied volt-
age?
Is current measurement avail-
able?
What is the maximum measuring
time using the battery pack?
What is the power consumption?
Can recording resume automati-
cally after a power outage?
Can power be supplied from the
HiLogger to an external sensor?

Remedial Action
Use the optional Hioki Z5000 Fixed
Stand.
Be careful to not exceed 300 V DC be-
tween channels (for the Universal Unit,
or 250V DC for the Voltage/Temp Unit),
or 300 V AC/DC to ground. For higher
voltage, avoid direct electrical contact,
such as by using non-grounding ther-
mocouples.
Measure by connecting a 250 Ω resistor
between + and - input terminals.
About 5 hours (@23°C)
Normal consumption is about 7 VA, and
maximum (while charging the battery
with maximum LCD brightness) is 24
VA.
Enable Auto Resume. Recording will
automatically resume after a power out-
age. Because data measured before the
outage is not retained in internal memo-
ry, we recommend enabling auto saving
to removable storage.
+12 V is provided at the external control
terminals. Maximum supply current is
100 mA. Ground is common with the
HiLogger.
