Can the HiLogger be installed at
an angle? Can it be mounted on a
wall?
Use the optional Hioki Z5000 Fixed
Stand.
"Chapter 11 Specifica-
tions":"Options (sold
separately)" (p .239)
How to measure the temperature
of an object having applied volt-
age?
Be careful to not exceed 300 V DC be-
tween channels (for the Universal Unit,
or 2
50V 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.
"4.1 Confirming Mea-
sured Values, and
Starting Measurement"
(p. 83)
: WARNING
Is current measurement avail-
able?
Measure by connecting a 250 resistor
between + and - input terminals.
"Connect a 4-20 mA
output device and
record the average val-
ue every minute"(p.
A28)
What is the maximum measuring
time using the battery pack?
About 5 hours (@23C) "2.2 Using the Battery
Pack (Option)" (p. 30)
What is the power consumption?
Normal consumption is about 7 VA, and
maximum (while charging the battery
with maximum LCD brightness) is 24
VA.
"Chapter 11 Specifica-
tions":"Power con-
sumption" (p .227)
Can recording resume automati-
cally after a power outage?
Enable Auto Resume. Recording will
automatically resume after a power out-
age. Because data measured before the
out
age is not retained in internal memo-
ry, we recommend enabling auto saving
t
o removable storage.
"Using the Auto-Re-
sume Function (Re-
sume After Power
Restoration)" (p .152)
Can power be supplied from the
HiLogger to an external sensor?
+12 V is provided at the external control
terminals. Maximum supply current is
100 mA. Ground is common with the
HiLogger.

tion (for external sen-
sors)" (p .42)
