Model 2100 rear panel 4-wire resistance measurement
How to measure resistance
1. Select input signal connections on front or rear panel.
2. Connect the test leads to the terminals as shown in Figure 3-6 (2-wire) or Figure 3-7
(4-wire).
3. Set the resolution (refer to “Resolution setting (digits)” in Section 4), or skip this step if the
default setting is used.
4. Press
2 key for a 2-wire measurement or SHIFT + 2 keys for 4-wire measurement.
5. Select the auto-range function by pressing the AUTO key on the front panel, or use the up
and down arrow keys to select the desired range.
6. Connect test leads to your source signal and observe the reading shown on the display. If
the input signal is greater than the allowed range, an overflow message ("OVLD") will be
displayed.
Frequency and period measurements
The Model 2100 uses an on-board counter with 25MHz to measure the frequency (period). The
measurement band is from 3Hz to 300kHz (or 333ms to 3.3
s), and the measurement voltages
range from 100mV to 750V in AC. The default setting for RANGE is “auto-range.”
WARNING The maximum input voltage allowed is 1000V. Applying excess voltage may
damage the meter and cause unpredictable hazards that may result in
personal injury or death.
How to measure frequency and period
1. Select input signal connections on front or rear panel.
2. Connect the test leads to the terminals as shown in Figure 3-2.
3. Set the resolution (refer to “Set ADC (Auto Zero and Auto Gain)” in Section 4) and input
jack, or skip this step if the default setting is used.
4. Press the FREQ button for frequency measurement or the SHIFT + FREQ keys for period
measurement.
5. Select the AUTO-RANGE function by pressing the AUTO key on the front panel, or use the
up and down arrow keys to select the desired range.
