Detailed Specifications
Accuracy is specified for a period of one year after calibration, at 18 C to
28 C (64 F to 82 F) with relative humidity to 90%.
Accuracy specifications are given as ([% of reading] + [number of least
significant digits])

For the 5,000 count mode, divide the number of least significant digits
(counts) by 10.
2
For relative humidity greater than 70%, resistance accuracy is 0.5%
over 1 M and 2.5% over 10 M .
3
For film capacitor or better, using Relative mode (REL ) to zero
residual on 1.1 nF range.
4 Reading will be 0.00 for signals below 0.5 Hz.
5
Least significant digit not active above 10 mF.
6 Using relative mode (REL ) to zero residual reading.
7
For ambient temperature changes of
1 hour.
8
For repetitive peaks, 2.5 ms for single events.
9
Frequency greater than 5 Hz, except for VDC, 500 mV dc and
3000 mV dc functions; 0.5 Hz to 1.0 + 0.
10
Range/input ratios also apply to current functions.
11 To ensure stated accuracy, switch to conductance mode and verify that
the open circuit reading is less than 0.10 nS.
12
Accuracy specification is relative to the user - adjustable temperature
offset, and assumes ambient temperature stable to
Above specifications are subject to change without notice.

Memory and PC Communication
Functions
(Fluke 189 Only)
The Fluke 189 adds the following capabilities:
Interval LOGGING At least 288 intervals (specified by user in Setup)
may be recorded to internal memory. These
values may be viewed using the VIEW MEM
function on the meter. Up to 700 unstable event
values (similar to AutoHold) are automatically
added to LOGGING memory for viewing only
through the optional FlukeView
software. Additional intervals will be logged if
the signal is stable.
Reading SAVE Up to 100 readings may be saved by the user in a
memory separate from LOGGING memory. These
readings may be viewed using VIEW MEM.
