Analog Bar Graph

Power-Up Options

Holding a button down while turning the meter on
activates a power-up option. Table 4 includes the power­up options available. These options are also listed on the
back of the meter.

Automatic Power-Off

The meter automatically turns off if you do not turn the
rotary switch or press a button for 30 minutes. To disable
automatic power-off, hold down the blue button while
turning the meter on. Automatic power-off is always
disabled in MIN MAX recording mode.

Input Alert™ Feature

If a test lead is plugged into the mA/µA or A terminal, but
the rotary switch is not correctly set to the mA/µA or A
position, the beeper warns you by making a chirping
sound. This warning is intended to stop you from
attempting to measure voltage, continuity, resistance,
capacitance, or diode values when the leads are plugged
into a current terminal. Placing the probes across (in

parallel with) a powered circuit when a lead is plugged
into a current terminal can damage the circuit you are
testing and blow the meter’s fuse. This can happen

because the resistance through the meter’s current
terminals is very low, so the meter acts like a short circuit.

Analog Bar Graph

The analog bar graph functions like the needle on an
analog meter, but without the overshoot. The bar graph is
updated 40 times per second. Because the graph
responds 10 times faster than the digital display, it is
useful for making peak and null adjustments and
observing rapidly changing inputs.

Model 87 Bar Graph

Model 87’s bar graph consists of 32 segments. The
position of the pointer on the display represents the last
three digits of the digital display. For example, for inputs
of 500 Ω, 1500 Ω, and 2500 Ω, the pointer is near 0.5 on
the scale. If the last three digits are 999, the pointer is at
the far right of the scale. As the digits increment past 000,
the pointer wraps back to the left side of the display. The
polarity indicator at the left of the graph indicates the
polarity of the input.

Models 83 and 85 Bar Graph

The bar graph on Models 83 and 85 consists of 43
segments. The number of lit segments is relative to the
full-scale value of the selected range. The polarity
indicator at the left of the graph indicates the polarity of
the input. For example, if the 40 V range is selected, the
"4" on the scale represents 40 V. An input of -30 V would

11

80 Series III

Users Manual

light the negative sign and the segments up to the "3" on
the scale.

If the input equals or exceeds the 4096 counts on a
manually-selected range, all segments are lit and±
appears to the right of the bar graph. The graph does not
operate with the capacitance or frequency counter
functions.

The bar graph on Models 83 and 85 also has a zoom
function, as described under "Zoom Mode".

4-1/2 Digit Mode (Model 87)

On a Model 87 meter, pressing the yellow button for one
second causes the meter to enter the high-resolution,
4-1/2 digit mode. Readings are displayed at 10 times the
normal resolution with a maximum display of 19,999
counts. The display is updated once per second. The
4-1/2 digit mode works in all modes except capacitance
and the 250 µs and 100 ms MIN MAX modes.

To return to the 3-1/2 digit mode, press the yellow button
only until all of the display segments turn on (about one
second).

MIN MAX Recording Mode

The MIN MAX mode records minimum and maximum
input values. When the inputs go below the recorded

minimum value or above the recorded maximum value,
the meter beeps and records the new value. This mode
can be used to capture intermittent readings, record
maximum readings while you are away, or record
readings while you are operating the equipment under
test and cannot watch the meter. MIN MAX mode can
also calculate an average of all readings taken since the
MIN MAX mode was activated. To use MIN MAX mode,
refer to the functions in Table 6.

Response time is the length of time an input must stay at
a new value to be recorded. A shorter response time
captures shorter events, but with decreased accuracy.
Changing the response time erases all recorded
readings. Models 83 and 85 have 100 millisecond and
1 second response times; Model 87 has 1 second,
100 millisecond, and 250 µs (peak) response times. The
250 µs response time is indicated by "1 ms" on the
display.

The 100 millisecond response time is best for recording
power supply surges, inrush currents, and finding
intermittent failures. This response time follows the
update time of the analog display.

The high-accuracy 1 second response time has the full
accuracy of the meter and is best for recording power
supply drift, line voltage changes, or circuit performance

Touch Hold ® Mode

WWarning

The Touch Hold mode will not capture
unstable or noisy readings. Do not use
Touch Hold mode to determine that circuits
are without power.

The Touch Hold mode captures the present reading on
the display. When a new, stable reading is detected, the
meter beeps and displays the new reading. To enter or
exit Touch Hold mode, press

I.

Relative Mode

Selecting relative mode ( C) causes the meter to
zero the display and store the present reading as the
reference for subsequent measurements. The meter is
locked into the range selected when you pressed

C. Press Cagain to exit this mode.

In relative mode, the reading shown is always the
difference between the present reading and the stored
reference value. For example, if the stored reference
value is 15.00 V and the present reading is 14.10 V, the
display shows -0.90 V.

On Model 87, the relative mode does not change the
operation of the analog display. Selecting relative mode
on a Model 83 or 85 meter causes the bar graph to enter
Zoom mode. In zoom mode, the center of the graph
represents zero and the sensitivity of the bar graph
increases by a factor of 10.

1. Accuracy is giv en as ±([% of reading] + [number of least significant digi t s]) at 18°C to 28°C, with relat i ve humidity up to 90%, for a
period of one year after calibrati on. For M odel 87 i n the 4 ½-digit mode, multiply the number of least significant digits (counts) by 10.
AC conversions are ac-coupl ed and valid from 5% to 100% of range. M odel s 85 and 87 are true rms responding. AC cres t factor can
be up to 3 at full scale, 6 at hal f scale. For non-sinusoidal wave forms add -(2% Rdg + 2% full scale) typical, for a c rest factor up to 3.

2. Below 10% of range, add 6 counts.

3. Models 85 and 87 are true rms responding met ers. When the input leads are shorted together in the ac functions, the meters display
a reading (typically <25 count s) that is caused by int ernal am pl i fier noise. The accuracy on M odel s 85 and 87 is not significantly
affected by this i nt ernal offset when measuring inputs that are within 5% to 100% of the selected range. When the rms val ue of the
two values (5% of range and internal offset) is calculated, the effect is m i ni m al as shown in the following example where 20.0 = 5% of
400 mV range, and 2.5 is the internal offset: RMS = SQRT[(20.0)
